• Probe selection: Thermocouple probes are purchased separately.

The Sato SK-L200THIIα temperature and humidity datalogger is discontinued and has been replaced by the Sato SK-L750 series.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.

• Existing equipment: Also identified as SK-L200THIIa or SK-L200THII alpha.
• Temperature and humidity replacement: SK-L754.
• Temperature-only alternative: SK-L751.
• Probe selection: Specify the required measurement range and sensor position when replacing your logger.

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Discontinued model: The AM-8000 series has been replaced by the Anritsu AM-9000 series.

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.

• Recording options: Up to three pens, depending on configuration.
• Chart drives: Battery-operated, with spring-wound and electric options available.
• Installation: Portable and fixed-mount configurations.

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).

The Evikon E2244 humidity and temperature transmitter measures relative humidity and air temperature for connection to controllers, monitoring instruments and building management systems.

• Analog outputs: 2 × 4–20 mA and 2 × 0–10 V.
• Construction: IP65-rated enclosure.
• Mounting: E2244 wall-mount and E2244-DM duct-mount versions.

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.

• Temperature and humidity: KT8 and TH8 models for temperature-only or combined temperature and relative humidity recording.
• Pressure: PW4 and PW8 families with 4-inch or 8-inch circular charts.
• Universal input: Legacy ET855 recorder information for existing voltage and current signal installations.
• Replacing an older recorder? Refer to the model comparison below before ordering a replacement or consumables.

The Isuzu TH27R (TH-27R) thermohygrograph is discontinued. For a replacement temperature and humidity chart recorder, choose the Sato NSII-Q (Sigma II).
