A p-type metal oxide VOC sensor VOC-A31 M31 P31 product introduction

This sensor is a broadband Total Volatile Organic Compounds (Total VOC) detector. When considering the cost of PID, the sensor can be used to detect 10 to 50ppb of VOC, depending on the type of VOC. Unlike common n-type sensors, this metal oxide sensor has a large dynamic range, a repeatable response, is less affected by humidity, and will increase resistance to most VOCs.

The sensor is available in 3 housings: TO-05 housing, 6-pin plastic housing and Ex explosion-proof housing.

Two p-type metal oxide VOC sensor VOC-A31 M31 P31 main features

1) Range: 1-100ppm isobutylene

2) Sensor resistance (R0):210 ±30 kΩ (50% rh, 23 (± 2)℃)

3) Sensor resistance (Rg):550 ±50 kΩ (isobutylene @ 10ppm<< span = ""> in air>)

4) Sensor resistance ratio (Rg/ R0 * 100%):260 ±30% (isobutylene @ 10ppm<< span = ""> in air>)

5) gas response relation (Rg/Ro - 1 = σ ki x Concn) : 0.5 +/- 10% (k for isobutylene)

where Ki = constant for gas I; n = 1 or 0.5: 0.5 (n for isobutylene))

6) Heater resistance (RH @ RT):10 ±1.5 Ω (23±1 ℃)

7) Heater resistance (RH @ sensing temperature):22 ±3 Ω (400±10 ℃)

8) Heater resistance (RH @ reset temperature):26 ±3 Ω (525±10 ℃)

9) Typical heating power consumption (mW) at 5:1 cycle: 340 ±30 (400 ℃) (VH = 2.7 ±0.2V)

530 ±50 (525℃)(VH = 3.7 ±0.3V)

10) Working temperature:-20~120 ℃
