3065 is an instrument which accepts pH and ORP sensors directly. We offer it configured as a meter for indication and local monitoring. The optional analog output allows it to be used as a pH or ORP transmitter to send the measurement to a data logger, recorder or remote monitoring device. It is also available with two or four SPDT 10 amp relay outputs which can be used as alarms or as control outputs
Imagine! A simple touch of a button and you’ll have 3065 series pH/ORP Meter/Transmitter/Controllers doing what you want it to do. All is easily done through menu selection and reading the ‘plain English’ prompts.
The Model 3065 series all have high impedance inputs that directly accept the output from standard pH and ORP probes through a BNC connector. Each 3065 is factory calibrated for the ideal response of the probes. With one and two point standardization, calibrating of the 3065 to a particular probe is readily accomplished by the front panel controls. The factory calibration may be reloaded at any time.
Other selectable features include: Displays pH as 0.00PH to 14.00PH and ORP as -2.500V to 2.500V. Up to 4 sets of on and off point control with 10 Amp S.P.D.T. contacts. The ability to name each control point a pump or an alarm. Flashing of display on trip. Security code lockout with latching and alarm acknowledgement. Sound horn on trip, trip acknowledgement, latch control on trip. Relay Failsafe Polarity.
The 3065 is housed in an 1/8 DIN aluminum housing with a splash proof front panel. The six digit 0.54 inch high LED display provides easy viewing under all ambient light conditions and it’s 14 segment alphanumeric display provides plain English prompting during configuration.
