If you are looking for a lightweight non-contact infrared thermometer that is easy to use then the ST350 should fit the bill. To operate all that is needed is to point the thermometer at the surface being tested and press the button. The large, clear LCD display will show the surface temperature of the item being tested.

Check your leaf surface temperature.

This quality infrared thermometer measures temperature over the range of -20 to 400°C (-13 to 752°F). It is accurate to ±2% of the reading ±2°C. It displays temperatures in 1°C or 1°F increments.

The thermometer has an auto power-off facility that turns the instrument off after 15 seconds in order to help maximize battery life.

The ST350 has a 10:1 optic ratio (target distance/diameter ratio). This means at a 30cm distance from an object it will be measuring an area of 3cm. The laser alignment ensures that the area to measure has been accurately targeted.  An emissivity is fixed at 0.95 making this instrument more suitable for heating, ventilation, and air conditioning testing as well as for testing engines, hot plates, chillers, etc.
