TDS meter GLI Pro

Accuracy:± 0.1 % of span, at 25 °C

Calibration Method:2-point Buffer (for pH only)
1-point Sample (for pH or ORP)

Communication:0/4 to 20 mA with 0.004 mA (12-bit) resolution (during calibration, the analog output is automatically held at the last measured value and, upon completion, returned to its active state)

Dimensions (H x W x D):95 mm x 95 mm x 60 mm

Display:2-line by 16 character LCD

Load:Maximum permissible load dependent on power supply voltage, transmitter hookup arrangement, and wire resistance

Material:Enclosure: Polycarbonate

Measuring Range ORP:-2100 - 2100 mV

Measuring Range pH:Selectable Ranges:
-2.0 - 14.0 pH
-2.00 - 14.00 pH

Measuring Range Temperature:-20 to 200 °C

Memory Backup:All user settings are retained indefinitely without battery backup

Mounting:Panel, wall, pipe, or integral sensor mounting

Operating temperature range:-20 - 60 °C at 0 - 95% RH (non-condensing)

Parameter:pH/ORP

Power requirements (Voltage):12 - 30 V DC

Relative Humidity:0 - 95 % non-condensing

Repeatability:± 0.05 % of span, at 25 °C

Response Time T90:1 - 60 s with output filter setting of zero

Sensitivity:± 0.05 % of span, at 25 °C

Special Notes:The measured pH (or ORP) and temperature can be displayed separately or together on one screen. Both analog output values are
shown together on one screen

Storage conditions:-30 to 70 °C 0-95% Relative humidity, non-condensing

Temperature Compensation:-10 - 110 °C
Automatic with selection for NTC 300 Ω, Pt1000 or Pt100 or manually fixed at a user-entered temperature; additional selectable temperature correction factors (ammonia, morpholine or user-set pH/°C linear slope)

Temperature Drift:0.02 % of span per °C (zero and span), at 25 °C
