Product Description
The pH analog controller with dual output and self-diagnostic test is supplied complete with mounting brackets and instructions. Inputs: BNC connector, Direct wire connection with amplified probe (supports HI 1006 series probes) and 4-20 mA from a transmitter. Auto-diagnostics to verify offset and slope calibration and electrode contamination/deterioration. Selectable manual ON, OFF and automatic dosing control for alkaline, acid and REDOX dosing with indicator. Dual set point with two independent dosing outputs. Extended temperature compensation range: -20 to 100 degree C. Supports potential matching pin connection. Both 4-20 and 0-20 mA output. +/-5V outputs for amplified electrodes. Backlit LCD. Fail Safe Function the alarm relay is activated at power down. Operational mode LED indicators. Transparent splash-proof cover. allows the selection of two set points with two independent outputs for acid and alkaline dosages. Each model accepts either a direct input from a pH or ORP electrode or from a transmitter through 4-20 mA input. The instrument also provides +/-5V power output and input terminals for amplified electrodes. In addition, you can choose the output configuration for connecting a recorder or a PLC, between 0-20 or 4-20 mA. The incorporates adjustable overtime dosing protection from 5 to 60 minutes. Range: 0.00 to 14.00 pH. Resolution: 0.01 pH. Accuracy at 20 degree C: +/-0.02 pH (0 to 100 degree C), +/-0.05 pH (-20 to 0 degree C), +/-0.5 percent (input from transmitter). Input: high impedance 10(12) Ohm; reference and matching pin inputs are available; 4-20 mA. Power output: +/-5 Vcc; 150 mA maximum load for amplified electrodes. Calibration: offset: +/-2 pH with offset trimmer, slope: 80 to 110 percent with slope trimmer. Temperature compensation: fixed or automatic with Pt100, from -20 to 100 degree C. Backlight continuous on. Enclosure: flame retardant ABS body and front panel; transparent splash-proof front cover. see details
