Effective Mar 22nd 2018, PHTX-11, PHTX-212 & PHTX-ORP models have been discontinued, effective Sep 25th, 2018 the PHTX-014 is also discontinued. As a possible substitute, please check out PHTX-100 series for details.
The model PHTX-014 pH two wire transmitter is designed
to provide a standard 4 to 20 mA current output which is
proportional to the pH being measured. Its small size and
encapsulated construction allow for easy installation and
will accommodate any pH electrode with a BNC connector.
Temperature compensation is either manual or automatic
with use of any 1000 Ohm Platinum RTD.
SPECIFICATIONS Range: 0 to 14 pH or 2 to 12 pH Span: 0 to 14 pH; Accuracy: ±0.02 pH; Operating Temperature: -25 to 70°C (-13 to 158°F); Input Impedance: 10^13 Ohms Temperature Compensation:
Manual: fixed resistors; Automatic: 1000 ohm Platinum RTD; Connector: BNC Power: 12 to 80 Vdc (24 Vdc recommended) Output: Non-isolated 4 to 20 mA; Dimensions: 57.4 H x 38.1 W x 38.1 mm D (2.25 x 1.5 x 1.5");
