Emerson 1056 Manuale Utente
1.3 SPECIFICATIONS — GENERAL
Sample requirements:
Pressure: 3 to 65 psig (122 to 549 kPa abs)
A check valve in the inlet prevents the sensor
flow cells from going dry if sample flow is lost.
The check valve opens at 3 psig (122 kPa abs).
If the check valve is removed, minimum pres-
sure is 1 psig (108 kpa abs).

. For higher
ranges, consult the factory.
pH correction range: 6.0 to 9.5. For samples having
pH between 9.5 and 10.0, consult the factory. If
pH < 6.0, correction is not necessary. For manual
pH correction, choose option -01. For continuous
pH correction choose option -02.
pH < 6.0, correction is not necessary. For manual
pH correction, choose option -01. For continuous
pH correction choose option -02.
Accuracy: Accuracy depends on the accuracy of the
chemical test used to calibrate the sensor.
Interferences: Monochloramine, permangante,
peroxides.
Electrolyte volume: 25 mL (approx.)
Electrolyte life: 3 months (approx.); for best results
replace electrolyte monthly.
