Essentials Dual Display Digital Thermo Hygrometer with Clock
A Vital Piece of Equipment for Every Grow Room - a Thermometer / Hygrometer
The Digital Thermo Hygrometer has 2 digital display: the top display is for local temperature (in C or F) and the other display is for the time and the local humidity (in RH). An accurate thermometer / hygrometer is an essential tool for monitoring your garden air environment.
- Dual display
- Displays the local temperature in either Centigrade or Fahrenheit (degrees C or F) from -50C to 70C (-58F to 158F)
- Simultaneously displays the time and local relative humidity (in RH 10% to 99%)
- Temperature accuracy: +/- 1C (+/- 2F)
- Temperature resolution: 0.1 degree
- Includes a max & min humidity and temperature function
- Takes 1 x AAA Battery (included)
- The rear includes a key-hole shaped hanging hole for wall hanging and a pull-out stand for sitting on a surface
1 x Dual Display Digital Thermometer & Hygrometer with Clock, 1 x AAA battery
How the Thermo Hygrometer Works
The top display gives a constant readout of the humidity or “dampness” of the local air. The bottom display gives a constant readout of temperature from it’s internal sensor. Temperature can be displayed in either Centigrade (Celsius) or Fahrenheit. The device remembers and can display the maximum and the minimum humidity & temperatures since the battery was inserted or the function was reset. The clock function can set to chime on the hour and can programmed with an alarm time. The unit itself has a clip-out stand and a key-hole recess on the back that so it can be hung from a screw. The unit is powered by one AAA battery (supplied).
How to Use the Thermo Hygrometer
Slide the battery cover off the back of the unit and insert the supplied AAA battery. As the unit is unit is facing with it's back towards you, the battery should be inserted into the lower half of the recess with the positive end of the battery (with the nipple) on the left. Replace the battery cover. Place the thermometer / hygrometer in the area where you wish to monitor the humidity/internal temperature by either pulling out the stand on the back to sit it on a surface or hang it on a small screw from it’s keyhole recess.
The local temperature around the unit is shown in the top display. The time and local humidity is shown on the bottom display. The temperature display can be toggled between Centigrade (Celsius) and Fahrenheit by pressing the C/F button. Pressing the Max/Min button once will display the maximum humidity and temperature reached since the battery was inserted. Pressing it again will then display the minimum humidity and temperature since the battery was inserted. Pressing it a final time returns the display to the current humidity and temperature.
The clock is set by pressing and holding the "MODE" button until the minutes begin to flash. The minutes can be increased by pressing the "ADJ" button once to increase the minutes by one for each press. Alternatively, if the "ADJ" button can be pressed and held in to quickly increase the minutes. Once the time in minutes is reading correctly then pressing the mode option which begins the hour time flashing. The hour time is adjusted in exactly the same manner as the minutes. Pressing the "MODE" button again will allow the clock to be set to 12hr mode or 24 hour mode. In 12 hour mode, the display will show an AM or PM symbol. Once the time has been set, pressing the "ADJ" button will display the date and month. These can be adjusted in a similar way to setting the time.
Pressing the "MODE" button will also change the display to the alarm time. This is set exactly the same way as the clock. When in alarm mode, the alarm can be set by pressing the "ADJ" button. Pressing the "ADJ" button cycles through switching the alarm on and off and the hourly chime on and off. When the Bell symbol is displayed then the Alarm is switched on. The speaker icon indicates that the hourly chime is switched on.
