The Contact Thermometer VIR50 is a 2200°C (3992°F) Dual Laser Video IR Thermometer with a color TFT LCD display of 5.6 cm (2.2 in) and a built-in VGA (640 x 480) camera. It comes with a MicroSD card for taking JPEG photographs and 3GP videos to view on your PC. Dual lasers represent the ideal measuring distance (about 127 cm) at which the two laser points converge on a 2.5 cm (1 inch) target spot. Includes a microSD card, a general-purpose Type-K bead wire probe, a USB cable, a rechargeable 3.7 V battery, a travel case, and a user handbook.

The HT200 is a heat stress WGBT meter that can accurately measure wet bulb globe temperature (WGBT), black globe temperature (TG), humidity (%RH), air temperature (TA), wet bulb (WT), and dew point (DEW). The Heat Stress Index assesses how hot it feels when humidity is paired with temperature, air movement, and radiant heat. Holds up to 50 readings. Comes with a 9V battery and a carrying case.

The HT30 Wet Bulb Globe Temperature (WBGT) meter measures the Heat Stress Index, or how hot it feels when humidity is mixed with temperature, air movement, and radiant heat. The meter can also detect individual temperature, humidity, and radiant heat, as well as monitor the impacts of direct solar radiation on an exposed surface using the Black Globe temperature sensor. An in/out function shows the WGBT value with or without direct sunlight exposure. Auto Power Off with override and an RS-232 interface are among the additional features. Comes with two AAA batteries.
