Model 201+ Continuous Monitor for VOC's, Inorganic & Fixed GasesClick here to enlarge
- 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

|Species measured:||Sensor(s):||Precision:||Response time:|
|Organics (VOCs by PID or FID) and inorganic species that can be ionized by the PID lamp (9.5, 10.6 or 11.7 eV)||Sensor(s): single- PID only or FID only||+/- 1-2% of reading||<2 sec. (PID) < 10s FID (to 90%) response|
|Sample flow rate:||Span Drift:||Range:||Linear Range:|
|> 1 LPM||<2% over 24 hours||0.1 to 6,000 ppm (optional ppb range)- PID
1 to 40,000 ppm FID
|Power consumption:||Dimensions:||Weight:||Instrument operating conditions:|
|< 50 watts maximum; 115 VAC, 0.4 amps||19'' Rack mount - 19'' W x 5 1/4''H x 14''D
Wall - 2''W x 21''H x 10''D
|19'' Rack mount - 12.2 pounds PID; 14 pounds FID
Wall - 19 pounds PID; 22 pounds FID
|5-40 degrees C, 0-95% RH (non-condensing)|
|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.|
