Sample flow

Between 100 and 500ml/min for optimum operation. Max 1 litre/mm.

Sample temperature

-5 to +40°C (non condensing)

Sample connections

Inlet and outlet: captive-seal compression fittings suitable for 0.25 inch (or 6mm) o/d tube

Speed of response

T90 - variable depending on sensor and concentration. Approximately 3s at % levels and 20s at ppm levels. The ppm figure assumes that the sensor is purged down to the ppm concentration of interest.

Analogue outputs

   E version 0 to 100%, 0 to 25%, 0 to 5%

   N version 0 to 100%, 0 to 25%, 0 to 5%, 0 to 5000ppm, 0 to 500ppm

   L & H version 0 to 5%, 0-5000ppm, 0-500ppm, 0-50ppm

Alarm outputs

 

Two alarms, each user-programmable for mode - HIGH, LOW

or OFF Hysteresis programmable from 0 to 10% of set point Volt-free changeover contacts rated at 250V r.m.s.a.c max., 3A max., max power 60W, normally energised.

Ambient temperature

 

0 to 40°C (continuous operation)

-5 to +55°C (intermittent operation)
