Rapidox 4100 electrochemical oxygen gas analyser: gas purity analyis

Analyzer dimension	250mm X 263mm X 150mm
Weight	3 kg
Power supply	110/120V or 220/240V, 50/60Hz; Max power consumption 4VA
Display	Multi-digit LCD - character height 12.7mm
Display ranges	E version - display range 0.01% to 100.0%. Suitable for samples containing mildly acidic gases; eg, carbon dioxide, hydrogen sulphide etc N version - display range 100ppm to 50% L version 0-1ppm to 5% (contains electrical solenoid valves to keep cell stored under inert gas) H version 0.1ppm to 10% (suitable for use with hydrogen containing gases only - contains electrical solenoid valves to keep cell stored under inert gas)
Display resolution	0.1% from 10% to 100% 0.01% from 0.50% to 9.99% 10ppm from 500ppm to 4999ppm 1ppm from 50ppm to 499ppm
Stability	Better than 2% of full-scale per month
Cell life	E version - up to 5 years N, L & H versions - up to 2 years
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	0 to 5V or 4 to 20mA (specify at time of order) Each user-programmable to the following spans: 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)
