Gilt Dial Max Min Thermometer & Hygrometer

This traditionally styled Dial Thermometer and Hygrometer features an attractive gilt bezel, clear, easy to read printed scales and pointers to show current, highest and lowest temperatures. 

By including pointers which show the recorded highest and lowest temperatures helps you to decide if night temperatures are falling low enough for you to require frost protection in the winter, or high enough at midday to need shading in your greenhouse in the summer.  

Whilst the hygrometer dial allows you to measure humidity, measuring the humidity in your greenhouse helps you to reduce the chances of plant disease. If you measure the humidity and it is consistently high you might need to take action to increase ventilation and air circulation.
