CWE Incorporated products

The GSM-3 Programmable Three-Channel Gas Mixer is designed to create precise custom gas blends from any three input gases, serving a range of industrial and experimental applications. The device features a user-friendly LCD display which presents the flow rates calculated based on selected total flow and concentration percentages for each gas component. Users can define and store up to four gas mixture configurations directly on the device, with further capabilities for extensive storage and recall of configurations using the provided GSM-CommVS software, compatible with Windows 7 and beyond. This software also includes a Sequencer for automated mixture control through simple programmable scripts, minimizing manual intervention. The GSM-3 supports most gases except explosive mixtures and is finely tuned for optimal flow control. Each unit can be tailored to suit specific applications by selecting appropriate flow controllers, ensuring accurate composition and balance with features like real-time bar graph displays and error checking mechanisms.

The TC-1000 Temperature Controller by CWE is designed for the precise monitoring and regulation of the body temperature of small animals, such as rats and mice. Utilizing a low-voltage DC proportional controller, it ensures artifact-free heating through a resistive heating pad. The system incorporates a Proportional-Integral-Derivative (PID) control mechanism to mitigate electrical transients associated with traditional on/off controllers. It features an easy-to-read front-panel LCD that displays critical parameters such as current body temperature, target set-point, alarm settings, and a heater power bar graph. An analog output translates temperature into a linear voltage, while compatibility with YSI-400 series thermistor probes offers versatile usage. Designed for ease of operation, the TC-1000 automatically adjusts for optimal performance and fault detection, ensuring reliable temperature control. The system is capable of supporting various heating devices by accommodating heater currents up to 10A via an external power source.

The CapStar-100 End-tidal CO2 Monitor offers precise and fast monitoring of carbon dioxide levels in rats and larger animals. Central to its design is a compact infrared analyzer noted for its stability and minimal maintenance requirements. It features a heated measurement cell crucial for preventing water condensation. Its graphic LCD provides CO2 concentration readings in both percent and mmHg, with options for breath-by-breath peak end-tidal and continuous rapid response monitoring. A single calibrated gas and room air simplify the calibration process. Designed for ease of use, it pairs effectively with SAR-830 series Small Animal Ventilators. Its capabilities extend to monitoring unassisted animals, making it suitable for a variety of research scenarios. The monitor has a response time capable of handling respiratory rates up to 100 breaths per minute. Accessories for convenient operation are available, and sampling rates allow accurate monitoring even for small animals like rats.
