Your pH electrode.
A portable meter to match.

PH850-A pairs the PH850 meter platform with a temperature probe so you can select your own application-specific pH electrode. Automatic calibration, a stability indicator and a rugged portable enclosure support routine pH testing.

Choose the electrode
for your sample.

PH850-A is the temperature-probe-only configuration of the PH850 platform. A pH electrode is not supplied, making it useful when you already own an appropriate BNC electrode or want to choose one for a specific sample.

Match the pH sensing glass and reference design to the sample, then confirm the meter connection. Organic solvents, high-viscosity samples, pure water and semi-solid foods can require different electrodes.

Calibrate with guidance.
Measure with a stable endpoint.

The platform supports one- to three-point automatic pH calibration and displays pH with temperature. A stability indication helps identify when the reading has settled.

Use fresh buffers that bracket the expected sample pH. Verify the selected buffer standard, connect the temperature probe and allow the sample to reach a stable temperature before recording results.

Field handling.
Bench convenience.

The IP57 instrument enclosure and protective boot suit portable work. A folding stand provides an angled view at the bench.

A rating for the meter enclosure does not give a connected electrode the same temperature or immersion limits. Keep plugs clean and dry and follow the electrode’s own care instructions.

PH850-A buyer questions

Is a pH electrode included?

No. This -A configuration is listed with a temperature probe only. Choose a compatible pH electrode separately.

Can I use a BNC pH electrode?

The platform accepts BNC pH electrodes. Confirm the electrode’s sample suitability and the separate temperature connection before ordering.

Why include a temperature probe?

The temperature probe supports temperature measurement and automatic compensation with a separate pH electrode that has no built-in temperature sensor.

What pH accuracy is specified?

The meter electronics are specified at ±0.01 pH ±1 digit. Actual sample performance also depends on the electrode, calibration and method.

How many calibration points does it support?

One to three points with automatic buffer recognition. Select the buffer standard required by your procedure.

Does it measure ORP?

The platform provides mV measurement with a compatible ORP electrode. The ORP electrode is separate.

Does this model export data?

The PH850 is the value platform. Choose PH8500 when USB output and GLP logging are required.

Do the parent-kit photos show everything included?

No. Platform/application photos may show a pH electrode or other items from a complete kit. The -A order is the temperature-probe-only configuration.

that fits your work.
