Available as an OEM circuit board, assembled and calibrated, the Model 1402 was intended for use with porous-electrode electrochemical sensors, but has since found use with many other sensor types and for some electrochemical applications. It is typically partnered with the Model 1401 Power Supply, and has been used as a building block in medium and large scale sensor testing systems. It features high sensitivity (1 nanoamp) and can drive up to 30 mA.
An indispensable tool for use in any lab dealing with gas sensors. The Model 1010 mixes gases in precise 1:50 to 50:1 ratios, without drift, for days or months at a time. It is commonly used to dilute higher concentrations of stock gases to arbitrary lower concentrations by dilution with air, nitrogen, or other gas. Mixing ratios are adjusted by a front panel dial, or remotely, using a data acquisition and control system. Many other uses have been found for the versatile Model 1010, such as controlling relative humidity in gas samples by mixing dry gas samples with water-saturated air.
