Model 201+ Continuous Monitor for VOC's, Inorganic & Fixed Gases

- The Model 201C is a continuous VOC Analyzer designed for continuous or process control. It has optional 4-20 mA output, RS485, MODBUS, 2-4 programmable setpoints, larger pump, bypass flow & and a 19” rack or industrial wall mount NEMA 4 enclosure.
- This 201C has the choice of one 9.5 or 10.6 eV lamp in a PID or an FID, Operator's Manual, configuration software and RS232 cable.
- The detectors are the PID or FID

Features
PID Lamps | FID | Enclosures | Programmable setpoints |
Our 9.5 and 10.6 eV lamps remain the best in the business since we developed them over 30 years ago. | Our very sensitive FID has flame out sensor that will shut off the hydrogen if the flame goes out | 19'' rack mount or NEMA 4 wall mount. | The 1-3 setpoints (depends on the options) can be programmed for PID control, above/below setpoints |
Display | ADC | Programmable Voltage/current output | Digital outputs |
Our 2 line by 16 character LED display is easy to read. The lower display is used for diagnostics. | Our 16 bit ADC provides a resolution of 1 part in 64,000 and our signal algorithm minimizes noise by signal averaging in the msec range. | 0-1VDC/4-20 mA. | RS485, MODBUS |
Ease of calibration- SemiAutomatic or Remote Automatic | The two point calibration for the PID uses an electronic zero (no zero gas needed) and a span gas. It is initiated by a push button switch. The time to calibrate is about 1 minute. The FID requires zero air and span gas for calibration. In the 201, the valving is built into the Analyzer. The remote calibration can be activated by a PLC controlled contact closure. |
