Product Type | Hygrothermograph | Temperature Measuring Range(°C) | -20 – 80 | Temperature minimal display(°C) | 1 |
---|---|---|---|---|---|
Drip-proof and Waterproof function | None | Operating Temperature Range(°C) | -20 – 50 | Humidity Minimal Display(%RH) | 3 |
Measured humidity range(%RH) | 0–100 | Paper sending speed(mm/h) | 20、10、5、2.5 | Outline(mm) | 300(W)×245(H)×105(D) |
Overall Accuracy | Temperature / ± 1°C, (0 to 50°C) Humidity / ± 3% RH (10 to 90% / at 25°C) | Features | Equipped with a large and easy-to-read digital display to be able to read the current value at a glance. Continuous recording for up to 6 months is possible by using folding chart paper which is convenient to handle. Standard range for temperature is -20 to 80°C, and for humidity is 0 to 100%. Readings are recorded at 1°C and 1% RH increments. Can record according to management conditions by changing the recording range, temperature 0 to 50°C (using special chart paper), etc. Achieves excellent linearity and stability, and boasts high accuracy and long-term stable measurement performance over the wide temperature range of -20 to 80°C. | Use | Can be used to collect data at laboratories in pharmaceutical companies, animal breeding rooms, etc. during research and development. Can be used for managing clean environments at bio and semi-conductor manufacturing plants, etc. Can be used to manage thermostatic ovens, environmental testing laboratories, fixed temperature warehouses, etc. Can be used to manage storage environments in museum and gallery display rooms, places housing cultural assets, etc. Can be used to manage cultivation environments for crops in places such as in mushroom plantations and greenhouses. Can be used to manage temperature and humidity in buildings, apartments, tunnel construction sites, etc. Can be used to manage indoor temperature and humidity in houses, offices, factories, hospitals, etc. |
