When hospitals, clinics and distributors look for a portable endoscopy system, they usually want three things: a compact imaging platform, the right scopes for their procedures, and a quotation that reflects what they actually need. Many sourcing projects stall because the processor and the scopes are evaluated separately, or because key details only come up after the first quote.
This guide uses the WeiRay WR-GP12.1 portable GI endoscopy image processor to show how a configuration comes together. It covers processor functions, scope choice for upper and lower GI work, and the checklist your team should prepare before asking for a quotation. Full product details are on the WR-GP12.1 Portable GI Endoscopy System product page.
Why a Portable Endoscopy System Is a Configuration, Not a Single Box
An endoscopy image processor needs a compatible scope to form a working imaging configuration. That is why WeiRay presents the WR-GP12.1 together with its compatible GI endoscopes, not as a stand-alone display unit.
In practice, buyers configure the system for:
- Upper GI (gastroscopy): WR-GP12.1 + a WR-WJA series digital gastroscope
- Lower GI (colonoscopy): WR-GP12.1 + the WR-CJA electronic colonoscope
- Combined upper and lower GI: one processor platform with both scope types
This modular approach lets you choose the scope diameter and working-channel size that match your equipment requirements. You do not have to accept a fixed bundle.
What the WR-GP12.1 Processor Brings to the Configuration
The WR-GP12.1 is a 12.1-inch portable endoscopy image processor. It combines the display, image controls, recording and air/water delivery in one compact unit.
Integrated 12.1-Inch Display
The processor has a 12.1-inch integrated display, listed at 1280 × 800 resolution. Because the viewing screen and processor are one unit, the basic system configuration stays compact and needs fewer separate core components.
Image Adjustment and Documentation
- White balance and brightness adjustment let users optimize the displayed image for the connected scope and viewing conditions.
- Still-image capture and video recording support case documentation and review workflows.
- Image quality is optimized with self-developed (proprietary) processing software, according to the WeiRay catalog.
Integrated Air/Water Pump
The WR-GP12.1 has an integrated pump for air and water delivery. This reduces the need for a separate basic air/water delivery device in the basic configuration.
Front-Panel Controls and Interfaces
Dedicated front-panel controls cover photo, record, freeze, mode, zoom, automatic white balance, pump, and light adjustment, so frequently used functions are within direct reach. The front panel also has a USB interface and the endoscope connection interface.
Choosing Scopes for Upper GI: WR-WJA Digital Gastroscopes
Three digital gastroscopes are compatible with the WR-GP12.1. They share an optical specification:
| Parameter | WR-WJA9530 / WR-WJA8026 / WR-WJA7020 |
|---|---|
| Field of view | 140° |
| Direction of view | Forward viewing |
| Depth of field | 3–100 mm |
| Light source | LED |
| Resolution | 1280 × 720 pixels |
| Working length options | 1050 / 1500 / 3000 / 3500 mm (listed for all three models) |
| Deflection angle | Up 180°; down 90°; left 90°; right 90° |
The main differences between the three models are insertion-tube outer diameter and working-channel inner diameter:
| Model | Insertion tube OD | Working channel ID | Selection cue |
|---|---|---|---|
| WR-WJA9530 | 9.5 mm | 3.0 mm | Largest gastroscope working channel in the series |
| WR-WJA8026 | 8.0 mm | 2.6 mm | Balance of slim diameter and channel size |
| WR-WJA7020 | 7.0 mm | 2.0 mm | Smallest insertion-tube diameter in the series |
The WeiRay catalog also lists these gastroscope design points: HD image quality, a water nozzle that helps keep vision clear during observation and treatment, and a waterproof one-touch connector described as suitable for immersion and disinfection.
How to Pick a Gastroscope
- Choose WR-WJA9530 when the 3.0 mm working channel is your main selection requirement.
- Choose WR-WJA8026 when an 8.0 mm insertion diameter and a 2.6 mm channel give the balance you prefer.
- Choose WR-WJA7020 when you need the smallest insertion-tube diameter in the series.
Choosing a Scope for Lower GI: WR-CJA Electronic Colonoscope
For colonoscopy, the WR-GP12.1 pairs with the WR-CJA electronic colonoscope:
| Parameter | WR-CJA |
|---|---|
| Field of view | 140° |
| Direction of view | Forward viewing |
| Depth of field | 5–100 mm |
| Light source | LED |
| Insertion tube OD | 12.8 mm |
| Working channel ID | 4.2 mm |
| Drug/water delivery channel | 1.0 mm |
| Resolution | 2 megapixels |
| Working length | 1680 mm |
| Deflection angle | Up 180°; down 180°; left 160°; right 160° |
The 4.2 mm working channel and separate 1.0 mm drug/water channel make the WR-CJA a clearly different configuration for lower-GI projects.
A Five-Step Selection Process for Buyers
| Step | Decision | What to check |
|---|---|---|
| 1 | Procedure category | Digital gastroscope for upper GI; WR-CJA for lower GI; or both |
| 2 | Insertion-tube diameter | 9.5 mm, 8.0 mm or 7.0 mm for gastroscopes |
| 3 | Working-channel size | 2.0–3.0 mm across the gastroscope series; 4.2 mm on WR-CJA |
| 4 | Working length | Gastroscope options of 1050 / 1500 / 3000 / 3500 mm; WR-CJA 1680 mm |
| 5 | Quotation package | Processor, scope models, accessories, market version and documentation |
Who Is This Configuration For?
The WR-GP12.1 platform is intended for these procurement scenarios:
- Hospital or clinic GI endoscopy equipment procurement
- Upper-GI, lower-GI or combined equipment configuration projects
- Endoscopy imaging setups where space is limited
- Medical-device distributors building a product portfolio
For distributors, one processor that supports several GI scopes makes it simpler to choose a product family and explain it to end customers.
What to Prepare Before You Request a Quotation
A quotation that lists only the processor does not describe a working system. To get an accurate, configuration-specific quote, send:
- Processor model and quantity
- Gastroscope and/or colonoscope models and quantities
- Working-length option for each gastroscope
- Required accessories and consumables
- Destination country and power-cord version
- Documentation requirements for your destination market
- Your technical-support requirements
On documentation: regulatory documentation can vary by product version and destination market, so list the documents you need in your inquiry.

Frequently Asked Questions
Can the WR-GP12.1 processor be used by itself?
No. The processor needs a compatible endoscope to form a working GI endoscopy imaging configuration. Choose at least one compatible gastroscope or the WR-CJA colonoscope when you request a quotation.
Which scopes are compatible with the WR-GP12.1?
The WR-WJA9530, WR-WJA8026 and WR-WJA7020 digital gastroscopes for upper GI, and the WR-CJA electronic colonoscope for lower GI.
Does the WR-GP12.1 record images and video?
Yes. It supports still-image capture and video recording for case documentation and review.
What is the difference between the three gastroscopes?
Mainly insertion-tube diameter and working channel: WR-WJA9530 is 9.5 mm with a 3.0 mm channel, WR-WJA8026 is 8.0 mm with a 2.6 mm channel, and WR-WJA7020 is 7.0 mm with a 2.0 mm channel. All three are specified at 1280 × 720 resolution with a 140° field of view.
