The Anritsu FL Series fiber optic thermometers measure temperature in microwave, high-frequency and high-voltage environments where conventional electrical sensors can be difficult to use.
Electrical interference can make temperature measurement difficult around microwave equipment, high-frequency processes and high-voltage components. The Anritsu FL Series provides a fiber optic sensing option for these environments, with dedicated probes selected to suit the measurement point.
Start with the number of channels required, then match the probe to the temperature range, material and installation conditions. The instrument's measurement range and the probe's operating range are different: the selected probe determines the usable range of the complete measurement system.

Specify the cable route and required installation length alongside the probe. Confirm fitting and seal compatibility where the probe enters a vessel or enclosed process.
Fitting options include TFE and Viton seal materials. Select the version to suit the installation and process conditions.
For a suitable configuration, provide the number of measurement points, expected temperature range, measured material, cable length and any exposure to chemicals or intense light. Include your required analog output or PC connection, supply voltage and quantity.
Contact us for pricing and availability. Include an existing instrument or probe model number if you need a replacement or an additional measurement channel.

The Anritsu FL Series fiber optic thermometers measure temperature in microwave, high-frequency and high-voltage environments where conventional electrical sensors can be difficult to use.
The Anritsu HD series handheld digital thermometers are discontinued and have been replaced by the Anritsu HR series .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.
Sato Digital Thermohygrometer PC-5400TRH is easy to read current temperature and humidity from a distance with large LCD (character height: 40mm) . Each min./max. value of temperature and humidity are simultaneously displayed. Alarm setting is available (buzzer sound and LED)
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
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 Sato SK-270WP-K waterproof digital thermometer replaces the SK-250WP for routine temperature checks in food preparation, production and laboratory work.
Anritsu MG Series Magnetic Probe are temperature sensors designed for stationary surfaces.
Built-in magnets allow these probes to be attached to measurement targets. Specific components may be combined to customize products for the needs of a customer's specific application.
The Sato SK-1260 digital thermometer combines portable temperature measurement with stored readings and high/low alarms. Dedicated Type K thermocouple and thermistor probes support different measurement tasks.
The Evikon E2218-DM duct humidity and temperature transmitter measures air conditions inside ventilation ducts and provides calculated dew point and absolute humidity values.
Check surface temperatures without contact using the Sato SK-8950 infrared thermometer. Its circular laser marker helps position the measurement, while IP54 protection supports handling with wet hands.

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® 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.
