Sato measuring instruments

Sato instruments cover temperature, humidity, atmospheric pressure, wind, rainfall, pH and liquid concentration. The range includes handheld meters, data loggers, chart recorders, transmitters, weather sensors, heat-stress monitors and timers.

SL Measurement helps you select the instrument, compatible sensor and accessories around your application. Start with what you need to measure and whether you require a local reading, recorded history or output to another system.


Contact thermometers and temperature probes

For contact measurements, choose the probe around the material, insertion depth and working conditions. Check the instrument and probe specifications together.

Temperature and humidity meters

Room-condition meters provide readings where staff can check them directly. Consider display visibility, sensor position and whether minimum, maximum or alarm functions are needed.

Temperature and humidity data loggers

Choose electronic logging when readings need to be reviewed over time. Match the number of channels, recording interval and probe arrangement to the measurement location.

Thermohygrographs and paper records

A thermohygrograph provides a visible paper history of temperature and humidity. Select the temperature range and recording period, then match the chart paper and pens to the recorder.

Temperature and humidity transmitters

For measurements sent to a controller or monitoring system, confirm the required output, power supply and sensor position.

  • Sato SK-RHC-I transmitter and probes — combines a local display with 4–20 mA outputs. Plug-in, remote-cable and slim remote probe arrangements are available; probes are sold separately.

Barometers and atmospheric pressure recorders

Choose a barometer for atmospheric pressure readings or a barograph to retain a paper record of pressure changes.

Wind and rainfall measurement

Weather measurement systems require compatible sensors and receiving equipment. Specify the installation position, cable length, power supply and required output when selecting the system.

pH meters and application-specific electrodes

For pH measurement, select the electrode according to the sample, temperature and measurement arrangement. Electrode dimensions and construction matter when working with small samples, test tubes or surfaces.

Refractometers for liquid concentration

Refractometers use refractive index to assess liquids on a specified measurement scale. Select the model according to the sample and expected concentration range.

WBGT heat-stress monitoring

WBGT instruments combine environmental measurements to help assess heat conditions at a measurement location.

Non-contact countdown timers

Dedicated timers provide a timing reference for repeated workstation tasks, preparation routines and handwashing stations.

  • Sato TM-27 and TM-29 timers — start a countdown by moving a hand over the sensor. Choose the model according to the required timing range and adjustment interval.

Probes, accessories and recording consumables

Use the full instrument model and accessory reference when ordering replacements. Similar-looking probes are not necessarily interchangeable, and measurement range depends on the selected instrument and sensor combination.

For paper recorders, provide the chart reference, measurement scale and recording period. Browse our recording consumables or check the individual recorder page for matching paper and pen references.

Request a Sato quotation

Send your model reference, quantity and required delivery date. If you need help choosing, describe the material or environment, measurement range and whether you need readings, records, alarms or an external output.

Include any probe, electrode, cable, chart paper or calibration documentation required with the instrument.
