Manufacturer-discontinued — available only while our remaining stock lasts. The Sekonic ST-50A (ST50A) displays temperature and humidity digitally while recording both readings on a paper chart.
A practical choice if you need another ST-50A to match an existing installation. The standard set includes one chart, a red recording pen and a blue recording pen. Replacement chart paper and recording pens are listed separately.
Take quick contact temperature readings with the compact Sato PC-9215 (1747-00). Its fixed stainless-steel probe measures from −50 to 150°C, while MAX/MIN and HOLD functions make readings easier to review.
This is the original drip-proof PC-9215, supplied with a clip-on probe sheath and an LR1130 button battery. Check the model number if you are replacing a PC-9215II; the two versions have different specifications.
Record temperature and humidity with the Sato SK-L754 data logger. Choose the probe position that suits your installation: SK-L754-1 plugs directly into the logger, while SK-L754-2 has a 1.6 m cable so the sensing tip can be positioned away from it.
Select your probe before adding to cart. Each option includes one SK-L754 logger and one selected probe. Price and availability update with your choice. The logger stores up to 16,000 readings per channel for later PC review.
Sekonic ST-50M (ST50M) is discontinued. This model combined temperature and humidity paper chart recording with SD card data storage. For a new instrument, shop Sato Sigma II for paper charts or shop Sato SK-L754 for electronic logging. Existing ST-50M users can still order compatible chart paper and recording pens below.
Sato PC-5410TRH is a digital temperature and humidity meter with a large LCD for checking indoor conditions at a glance. Current readings and the highest and lowest values are displayed together.
Keep your existing Sato SK-L200THIIα temperature and humidity datalogger in service. Choose the SK-LTHIIα-1 plug-in probe or the SK-LTHIIα-2 remote probe with 1.5 m cable. Each option is one replacement probe only; the discontinued logger is not included.
Select your probe model to see its price and stock status. These legacy probes are not interchangeable with probes for the newer SK-L754 datalogger.
See the current, highest and lowest temperature together with the Sato PC-3500 digital thermometer. Connect its supplied 3 m probe to measure away from the display, or disconnect it to use the built-in sensor.
Manufacturer-discontinued; available while remaining stock lasts. This listing is for the PC-3500 (Cat. No. 1740-50) with its external probe and LR44 battery. Press RESET when starting a new monitoring period or switching measurement locations.
Check temperatures in food preparation, production and laboratory work with the Sato SK-270WP-K. This ready-to-use set includes the S270WP-01 standard probe, which measures from −40.0 to 250.0°C.
The thermometer starts measuring when switched on and has a HOLD function for reading the display. Its body is IP67 rated when the probe is correctly connected. Two AAA batteries, a neck strap and a protective vinyl cover are included.
The Dickson SL4100 records temperature on a 4-inch circular chart while showing the current reading on its LCD. Select a 24-hour or 7-day chart rotation to suit your monitoring schedule.
Keep a visible paper record of temperature and humidity with the Sato Sigma II NSII-Q thermohygrograph. Its clear cover lets you check the chart at a glance, while the quartz clock supports 1-day, 7-day or 32-day recording.
Choose your temperature range: 7210-00 measures −15 to 40°C; 7211-00 measures −10 to 50°C. Both measure 0 to 100% RH. Select the model that matches your site conditions before adding to cart.
Humidity and temperature at a glance. The Sato Highest I (7540-00) pairs a precision hair hygrometer with a glass thermometer in one easy-to-read instrument. Check 20–100% RH and −10 to 50°C during routine indoor inspections, without batteries or a data logger.
Compact logging for temperature and humidity. The testo 174H monitors indoor conditions with two built-in sensors, an easy-to-read display and memory for up to 16,000 readings. Ideal for storage rooms, archives and routine environmental checks. This listing is for the logger only: a compatible USB interface is required to set it up and download data.
Isuzu TH27R is discontinued. For a new temperature and humidity paper chart recorder, choose the Sato Sigma II 7210-00 or 7211-00 according to the temperature range you need. This TH27R page is retained to help identify existing instruments and their consumables; the TH27R itself is no longer available to order.
Check heat conditions at worksites, sports facilities and outdoor activity areas with the Sato SK-170GT WBGT monitor. Its built-in black globe accounts for radiant heat while the instrument displays WBGT, air temperature, globe temperature and relative humidity.
Choose indoor or outdoor measurement mode, set a WBGT alarm and review maximum or minimum readings. One 9 V battery and a hard carrying case are included.
Record up to six measurement points on one paper chart with the Sekonic SP-100 portable hybrid recorder. Configurable inputs support thermocouples, resistance thermometers, DC voltage and current measurement.
Manufacturer-discontinued; offered from remaining stock. The chart gives operators a visible record on site. Temperature sensors, a current-input shunt and the optional memory-card unit must be selected separately as required for your application.
Check temperatures, save readings and receive an audible alert when a set limit is reached. This Sato SK-1260 set includes the SK-S100K Type K probe for liquids, viscous liquids and semisolid materials.
The supplied probe is rated from −100 to 300°C; the meter displays readings from −99.9°C with this probe. The set also includes four AAA batteries, a carrying pouch and an instruction manual. Other probes and the printer are sold separately.
