Choose digital thermometers, infrared thermometers and humidity meters for production checks, maintenance, laboratory work and indoor environmental measurements. SL Measurement offers Anritsu and Sato instruments with different probe arrangements, displays and recording functions.
Start with the measurement task: surface temperature, internal temperature or the temperature and relative humidity of the surrounding air.
A contact thermometer uses a compatible probe to measure the target. The Anritsu HR series handheld digital thermometer offers Type K or Type E thermocouple models, with different display and memory functions.
Select the probe alongside the instrument. Surface shape, insertion depth and access affect which sensing arrangement is suitable. Confirm the thermocouple type and connector before reusing an existing probe.
Browse our temperature probes for surface, immersion and other contact measurement tasks. Check whether the selected thermometer includes a probe or requires one to be ordered separately.
An infrared thermometer measures surface temperature without touching the target. The Sato SK-8950 infrared thermometer includes adjustable emissivity and a circular laser marker to assist positioning.
Check the measurement distance, target size and surface material before selecting an instrument. Infrared readings represent the surface; use a suitable insertion probe when the temperature inside a material is required.
A thermohygrometer measures air temperature and relative humidity together. These instruments support routine checks in rooms, storage areas and workspaces where both readings matter.
The Sato Highest II temperature and humidity meter combines a humidity dial with a digital temperature display. When comparing instruments, consider the measuring range, readability, sensor location and whether minimum/maximum readings or alarms are needed.
For ongoing records or connection to a control system, explore our temperature and humidity recorders, data loggers and transmitters.
Tell us what you need to measure, the expected range and the accuracy required. For temperature measurements, describe the target material and how the probe will reach it. For humidity measurements, include the installation location and expected air conditions.
If replacing an instrument, send the full model code and existing probe reference. Include any requirements for memory, alarms, printed records or calibration documentation.

The Sato NSII-Q Sigma II thermohygrograph records temperature and relative humidity together on a rotating paper chart. Its quartz-driven mechanism provides a visible measurement history for routine environmental checks.
The Sekonic ST-50M thermohygrograph records temperature and relative humidity on paper charts and an SD memory card. Its digital display provides local readings, while recorded electronic data can be reviewed on a computer.
Discontinued: The ST-50M is no longer available as a new instrument. This page provides reference information, consumable part numbers and alternative recording options.
The Sekonic ST-50A digital thermohygrograph combines an electronic temperature and humidity display with continuous paper chart recording. View current conditions and retain a physical record for environmental checks.
Discontinued model: Manufacturer sales have ended. Remaining stock, consumables and alternative instruments are subject to availability.
The Anritsu HD series handheld digital thermometers are discontinued and have been replaced by the Anritsu HR series .
For a replacement, match the instrument to your thermocouple type, probe connector and measurement requirements.
The Anritsu AP-400 and AP-450 printing thermometers produce temperature records directly at the measurement point. Use manual printing for inspection rounds or interval printing to follow temperature changes.
The Anritsu AM-8000 series temperature datalogger is a portable instrument available in 6- and 12-channel models for recording multiple measurement points. Internal memory stores readings for transfer to a PC using dedicated software.
Discontinued model: The AM-8000 series has been replaced by the Anritsu AM-9000 series.
The Sato SK-L200THIIα temperature and humidity datalogger is discontinued and has been replaced by the Sato SK-L750 series. For recording both temperature and relative humidity, select the SK-L754 with a suitable probe.
The Sato SK-RHC-I temperature and humidity transmitter combines a local display with 4–20 mA outputs for connection to compatible monitoring and control equipment. Three interchangeable probe designs support different sensor positions.
Probe sold separately. An optional AC adapter is available.
The Sato Highest II 7542-00 temperature and humidity meter combines a humidity dial with a digital temperature display for straightforward checks of indoor conditions.
Measure stationary surface temperatures with Anritsu A Series contact probes. Select the head size, guard and shaft arrangement to suit the measurement point and operating temperature.
Need help maintaining surface contact as the holding angle changes? Compare the Anritsu AX Series flexible-head surface probe.
Measure small stationary surfaces with Anritsu CS Series micro surface temperature probes. Choose the sensing head, shaft arrangement and connector to suit the measurement point and your thermometer.
Attach an Anritsu MG Series magnetic temperature probe to a suitable stationary metal surface for contact temperature measurement. Built-in magnets hold the sensing head in position, reducing the need to maintain pressure by hand.
