H2O Scientific

The economical PRO-P3 Transmitter is easy to use with its menu-guided user interface. The NEMA 4X enclosure can be panel, wall, pipe, or integral sensor mounted. The interface is identical to GLI's 33-series analyzers. Versatile 2, 3, or 4-wire hookup capability. Isolated 4 - 20 mA output. The transmitter is also passcode protected.

• Multiple Measurements (pH, ORP, temperature, analog output value)
• Multiple Language Capability
• Versatile Sensor Compatibility
• Auto/Manual Temperature Compensation
• Simple Interactive Diagnostics

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)

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

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.

Temperature Compensation:
-10 - 110 °C

Automatic with selection for NTC 300 deg C, 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).
