The SDL400 records data on an SD card in Excel format. Wide range to 10,000Fc or 100kLux. Cosine and color-corrected measurements. Utilizes precision silicon photo diode and spectral response filter. Offset adjustment used for zero function to make relative measurements. Adjustable data sampling rate. Stores 99 readings manually and 20M readings via 2G SD card. Type K/J Thermocouple input for high temperature measurements. Large backlit LCD display. Record/Recall Min, Max, Data Hold and Auto power off.

Extech’s DT60M measures distance up to 196ft (60m). It can calculate area and volume and the integrated Pythagorean Theorem allows the user to take indirect measurements. Other features include continuous measurement with Min/Max distance tracking, 20 point memory, addition/subtraction of sequential readings, front or rear edge reference, and a Stakeout function. Large quad backlit LCD display and double molded housing. It also has a handy built-in bubble level and comes with a wrist strap.

The T-10A is a illuminance meter that will quickly show on the LCD screen the illumination and average values of measurements. You can easily compare illuminance values and have them shown either in a percentage or a difference value.

Compact, lightweight, easy-to-use SLR luminance meters with a wide measuring range. 1/30 acceptance angle. Measuring range: 0.01 to 999,900 cd/m2. The user calibration function allows the meter to be calibrated to a user-selected standard instead of the preset Konica Minolta standard; this function can be used to standardize the response of several meters.

The EA33 takes high intensity light measurements. Using the EA33's 50-reading memory, this light meter can store up to 50 measurements with either a relative or a real time clock stamp.
