PHGA-1 ECS Protector Handheld Gas Analyzer

Nitrogen Generator Corrosion Monitoring

General Description

The ECS Protector Handheld Gas Analyzer (PHGA-1) provides the concentration of nitrogen gas when connected to an ECS product with a gas sample port. The handheld analyzer can be used to verify nitrogen concentration inside a fire sprinkler system or at the outlet of an ECS Nitrogen Generator System. The ECS Protector Handheld Gas Analyzer provides the end user with a simple, cost effective method of gas concentration monitoring.

Operational Information

Nitrogen purity level in the fire sprinkler system can be checked by inserting the ECS Protector Handheld Gas Analyzer (PHGA-1) into the nitrogen sampling port in the equipment.

  1. Power On the PHGA-1 by depressing the power on button.
  2. Calibrate the PHGA-1 by depressing and holding the calibration button for three (3) seconds until “CAL” is displayed.
    NOTES: To calibrate analyzer, unscrew sampling hose from analyzer and move back and forth until reading is displayed. a. PHGA-1 must be recalibrated if nitrogen percentage displayed is above 80.1% or below 78.1% when reading normal atmosphere, not connected to the nitrogen generator cabinet/vent. b. Recommended to recalibrate analyzer daily when in use.
  3. Once the PHGA-1 is calibrated, insert the quick disconnect of the sampling hose into the sampling port in the nitrogen generator cabinet/vent.
    NOTES: a. Nitrogen generator must be operating in “nitrogen production mode” to sample nitrogen in cabinet.
    b. Vent must be open to sprinkler system pressure to sample nitrogen in sprinkler system.
  4. Allow 1 minute for the PHGA-1 to stabilize, verify and document reading on PHGA-1 (nitrogen level should be approximately 98%). If nitrogen level from generator is below 96%, contact ECS.

Operational Information

  1. Elevation changes will affect the accuracy of the nitrogen purity readings. The deviation of the nitrogen purity can be approximately 1% per 250 feet of elevation.
    a. Calibration of the instrument should be performed when elevation at which the product used changes more than 500 feet above sea level.
  2. Temperature effects the accuracy of the nitrogen purity readings. The gas analyzer will hold calibration and correctly read nitrogen purity ±3% when thermal equilibrium within the operating temperature range. The device must be thermally stable when calibrated and allowed to thermally stabilize after experiencing temperature changes before readings are accurate.
    a. For best results, perform the calibration procedure at a temperature close to the temperature where analysis will occur.
    b. Allow adequate time for the sensor to equilibrate to a new ambient temperature
    CAUTION: “CAL Err St” may result from a sensor that has not reached
