Temperature and humidity data loggers, chart recorders and transmitters help you monitor conditions, retain measurement records and connect sensors to control systems. SL Measurement supplies instruments for environmental monitoring, storage areas, laboratories and process measurements.
Choose a data logger for electronic records, a chart recorder for a visible paper history, or a transmitter to send measurements to another instrument or system.
Data loggers capture readings at selected intervals for later review. Start with the measurement range, number of channels, recording duration and method of downloading your results.
Chart recorders provide a measurement history that can be checked directly on paper. Match the measurement range, recording period and chart format to your record-keeping requirements.
For ongoing monitoring, consider how staff will view readings, receive alarms and retrieve measurement history. Check network access, sensor placement and any software subscription required.
Transmitters send measurement signals to controllers, building management systems or external recorders. Confirm the required output, power supply, installation position and receiving instrument before selecting a model.
The probe must suit both the instrument and the measurement conditions. Check the sensor type, connector, temperature range, cable length and exposure to moisture before ordering.
Browse our temperature probes or refer to the selected instrument page for its dedicated sensor options. Probes are not interchangeable across all models.
Send your application, measurement range, number of monitoring points and preferred recording method. For replacements, include the existing instrument and probe model numbers. For chart recorders, include the chart paper and pen references where available.

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Discontinued model: The AM-8000 series has been replaced by the Anritsu AM-9000 series.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 Anritsu AM-9000 series temperature datalogger records measurements across 6 or 12 channels, with fixed thermocouple and multi-input models available. Store readings in internal memory and transfer them to a PC through USB using optional AMS-950 analysis software.
AMS-950 software is sold separately.
Dickson circular chart recorders provide a paper record of temperature, humidity, pressure or external transmitter signals, depending on the model. Select the recorder by measurement type, chart size, recording period and installation requirements.
Dickson OCEAView™ brings wireless environmental monitoring, alarm notifications and traceable records into one platform. Monitor temperature, humidity and other critical parameters using compatible data loggers and sensors for refrigerators, freezers, laboratories, pharmaceutical storage and cold rooms.
The Dickson TWP touchscreen data logger displays readings and measurement history on an 8-inch colour screen. Configure it for temperature, humidity or differential pressure monitoring using compatible replaceable sensors.
The Evikon E2218-DM duct humidity and temperature transmitter measures air conditions inside ventilation ducts and provides calculated dew point and absolute humidity values.
The Evikon E2244 humidity and temperature transmitter measures relative humidity and air temperature for connection to controllers, monitoring instruments and building management systems.
The Isuzu TH27R (TH-27R) thermohygrograph is discontinued. For a replacement temperature and humidity chart recorder, choose the Sato NSII-Q (Sigma II).
Monnit ALTA Wireless Humidity (RH) Sensor allows you to accurately monitor the relative humidity of the air within a room or enclosure. - Measures relative humidity, temp
Monnit ALTA Soil Moisture Sensor measures soil moisture tension & soil temperature within the soil. It uses a resistive granular matrix element to accurately measure the matric water potential (soil moisture tension) in the soil and a thermistor based temperature element to measure temperature.
- Safe to use in both hot & freezing temperatures
- Reports matric potential (soil water tension)
- Moisture readings in centibar & kPa
- 0 to 240 centibar (kPA)
- Will not dissolve in soil
- Internally compensated for commonly found salinity levels
- Easy to install and use compared to traditional tensiometers
- Stainless steel electrodes
- No maintenance required
- Temperature readings in C/F.
- 5 ft removable lead
Monnit ALTA® Wireless Thermocouple Sensors leverage Monnit’s award-winning remote monitoring platform to remotely monitor high-temperature applications, such as commercial ovens, kilns, and chimneys. Users benefit from a wireless data transmission range of 1,200+ ft, bank-grade security, and a temperature range of up to 400°C (752°F).
Monnit’s thermocouple is user-programmed to sleep for a specified interval, awake, capture analog data, and then convert this measurement into a temperature. If the sensor captures temperatures outside of user-specified thresholds, an alert is sent via text, email, or call. Monnit’s hardwired thermocouples feature a needle-style probe at the end of a 6’ lead (a K-Type Quick Connect Thermocouple is also available).
Palmer Wahl pressure and temperature chart recorders provide a paper record of measurements over time. Choose an 8-inch or 12-inch recorder with an aluminium or Pelican® case, configured for pressure, temperature or combined recording.
Sato Mini-Cube 7008-00 compact thermohygrograph for continuous 7-day recording of temperature and relative humidity.
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 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.
Monitor four measurement points with the Sato SK-L400T 4-channel temperature data logger. Connect Type K thermocouple probes, view all four readings together and record temperature data to an SD card.
The Sato SK-L750 series data loggers record temperature or temperature and humidity for later review on a PC. Choose the SK-L751 for two-channel temperature measurement or the SK-L754 for combined temperature and humidity recording.
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.
