temperature/humidity are measuring instruments that measure the temperature and humidity of air and gases. They are used for temperature/humidity control in a variety of locations, from monitoring indoor environments to manufacturing and storage process and testing facilities.
For more information on the basics of humidity and the differences between relative humidity, absolute humidity, and dew point temperature, please see "What is Humidity?".
When choosing temperature/humidity, it's important to consider not only the temperature and humidity range to be measured, but also the measurement location, operating environment, and sensor installation method. Depending on your application, you can choose from various types including insertable, separate, wall-mounted, handheld, and ventilated models.
| Insertion Type | Separate type | Wall Mounting Type | Handy type | Ventilated type |

HN-CP□ Temperature: 0~80℃ Humidity: 0-100% rh (Prevent dew condensation) |
HN-CJ Temperature: -40~180℃ Humidity: 0-100% rh (Prevent dew condensation) |
HN-EK□ Temperature: -10~55℃ Humidity: 0-100% rh (Prevent dew condensation) |
HN-EH□ Temperature: -20~70℃ Humidity: 5-95% rh (Prevent dew condensation) |
MH6 Temperature: 0~60℃ Humidity: 0-100% rh (Prevent dew condensation) |
There are various methods of measuring humidity, and the most suitable method depends on the measurement environment and the required accuracy. For the basics of humidity measurement and types of hygrometers, please see "What is Humidity?".

| Humidity Range | 0~100%rh |
| output | Temperature, relative humidity |
| Explosion proof structure types | Intrinsically safe explosion proof structure (Ex ia ⅡC T4 Ga) |
This is a wall-mounted temperature/humidity (intrinsically safe explosion proof structure) for measuring temperature/humidity in explosion proof environments.
| Models | MH6 |
| Temperature range | 0~60℃ |
| Humidity Range | Relative humidity: 0 to 100%rh or saturation: 0 to 48g/ m3 *Please designate models when purchasing |
This is a thermal conduction type hygrometer/saturation differential meter for use in test rooms prone to high humidity and in environments for raising animals and plants.
| Models | HN-EH |
| Temperature range | Integrated type -10 to 45℃ Probe type -20 to 70°C |
| Humidity Range | Relative humidity: 5 to 95% Dew point temperature: -35 to 55°C (standard type only) |

| Models | R220 |
| Temperature range | 0~60℃ |
| Humidity Range | 20-80%RH |
| output | Dry bulb terminal (DRY), wet bulb terminal (WET) |
The R220 series is a ventilated dry-bulb/ temperature/humidity-bulb temperature and humidity sensor. The two temperature detecting element for the dry bulb and wet bulb use platinum resistance thermometer.
| Models | R320 |
| Temperature range | 0~100℃ |
| Humidity Range | 20-100%RH |
| output | Dry bulb terminal (DRY), wet bulb terminal (WET) |
The R320 series is a wet-and-dry-bulb temperature/humidity sensor. Since it does not have a ventilation system, it is intended for measuring temperature/humidity in places such as ducts where the wind speed is always 3 m/s or more.
