PPB MiniPID 2: range 1 ppb – 40 ppm

The PPB variant is used for high sensitivity in the part per billion (ppb) range with minimum detection limit of 1 ppb. The PPB sensor is optimised to deliver an exceptionally low background current allowing for optimum low-end sensitivity.

Minimum detection limit：20 ppb
Range：＞200 ppm
T90 response time: ＜8 s
Typical responsivity：＞5 mV/ppm
Offset voltage：51～80 mV
Output voltage：Offset voltage to rail voltage - 0.1 V
Lamp life：10,000 hours continuous operation
Power consumption：100 mW at 3.3V (100 ms 130 mA transient upon switch on)
Temperature range：-40°C < T < 55°C
Humidity range：0 - 99% RH, non-condensing
Humidity sensitivity：Humidity resistant
Expected life：> 5 years (excluding replaceable lamp and pellet)
Warranty period：12 months
