TB600B series TVOC module has many high-precision detection technologies from Sensor and circuit team together. The sensor uses the world's smallest solid polymer sensor from EC Sense, Germany. It can replace our nose to sniff out the gas concentration accurately, and realize accurate gas detection. The module uses UART digital output, make easy for customer use, eliminating the need for customers to understand the sensor application and the tedious work of
calibration.
TB600B-TVOC-10 Organic Volatile Gas Module Features
Principle |
Solid Polymer Electrochemical Sensing Technology |
Order number | 04-TB600B-TVOC-10-01 |
Detection of gas | TVOC Organic Volatile Gases |
Detection Range | 0 - 10ppm; Best detection range: within 5ppm; Display resolution: 0.001ppm |
Lowest Detection Limit | 0.01ppm |
Full-scale accuracy error | ±5% F.S |
Settling time | Stored in clean air for the first time power on <120 seconds |
Storage in non-clean air for the first power-on <240 seconds (except in the presence of high concentrations of polluted gas) | |
Response time | <3 seconds ( T50: <40 seconds; T90: <80 seconds; T100: <180 seconds;) |
Return zero time | 10ppm return to zero (below 0.03ppm) <80 seconds (return to zero in a relatively clean environment requiring ventilation) |
5ppm return to zero (below 0.03ppm) <120 seconds (return to zero in a relatively clean environment requiring ventilation) | |
Calibration substance | 10ppm measurement range: 5ppm is obutene C4H8 gas calibration |
Note: The smaller the range is, the higher the detection accuracy is. It is not recommended that users use it beyond the range. |
