The Sato SK-L200TH II has been discontinued. The replacement is the Sato SK-L754 temperature and humidity data logger. Select the SK-L754 with a compatible probe to suit the measuring location and operating range.
View the Sato SK-L754 replacement and probe options.
The SK-L200TH II recorded temperature and relative humidity for reviewing conditions over time. This page retains information for existing users, including the SK-L200TH IIα and its probe references shown in the original listing.
The SK-L754 provides electronic temperature and humidity recording with a local display, USB communication and microSD data transfer. Use the dedicated software to configure recording, review graphs and export CSV files.
Choose SK-L754 for temperature and humidity. The SK-L751 in the same product family is a temperature-only logger.
| Probe | Configuration | Temperature range | Humidity range |
|---|---|---|---|
| SK-L754-1 / 8880-01 | Plug-in probe for measurements at the logger | −10 to 60°C | 5 to 95% RH |
| SK-L754-2 / 8880-02 | Remote probe with 1.6 m cable | −20 to 80°C | 5 to 95% RH |
The cabled probe's wider range does not extend the logger body's permitted ambient conditions. Keep the SK-L754 body within −10 to 60°C and below 85% RH, without condensation.
The original page's detailed specifications identify the SK-L200TH IIα. Check the label on your instrument before using these details for an earlier SK-L200TH II unit.
