SAMPLE REQUIREMENTS
Pressure: 3 to 65 psig (122 to 549 kPa abs) Inlet check valve opens at 3 psig (122 kPa abs). If the check valve is removed, minimum pressure is 1 psig (108 kpa abs).
Temperature: 32 to 122°F (0 to 50°)
Flow: 3-80 gal/hr (11-303 L/hr)
Sample Conductivity: >10 μS/cm at 25°C
Process connection: ¼" OD tubing compression fitting (can be removed and replaced with barbed fitting for soft tubing).
Drain connection: ¾" barbed fitting. Sample must drain to open atmosphere.
Wetted parts: acrylic, nylon, polycarbonate, polyester, Kynar, silicone, Noryl, Viton, silicone, and Zitex, PTFE, (Gold mesh cathode - not normally wetted)
Response time to step change in monochloramine concentration: <60 sec to 95% of final reading for inlet sample flow of 17 gph (64 L/hr).
Weight/shipping weight: 10 lb/13 lb (4.5 kg/6.0 kg)

SPECIFICATIONS — SENSOR
Range: 0 to 6 ppm as Cl2. For higher ranges, consult the factory.
pH range: Signal is practically independent of pH between pH 7.0 and 10.0. Sensor current at pH 10.0 is within 5% of sensor current at pH 7.0.
Accuracy: Accuracy depends on the accuracy of the chemical test used to calibrate the sensor.
Linearity: 2% (typ.)
Electrolyte volume: 25 mL (approx.)
Electrolyte life: 2 months (approx.)

Ordinary Location (option -68 only):
 POLLUTION DEGREE 2: Normally only non-conductive pollution occurs.
 Occasionally, however, a temporary conductivity caused by condensation
 must be expected.
