Extech 407732-KIT Low/High Range Sound Level Meter Kit, Plastic, 9V battery

Ideal for monitoring environmental conditions (temperature, humidity and dew point) in laboratories, storage areas, manufacturing assembly areas and other controlled environments, the humidity alert meter features a user settable alarm and will warn you, both audibly and visually, when adverse conditions occur. High humidity can create a breeding ground for mold and low humidity can create static electricity. The 445815 also displays the dew point reading which is a calculation of temperature and humidity and used to determine when condensation will occur. The humidity alert meter ...

Easy to set area dimensions (cm2) are stored in the meter's internal memory for the next power on. Features: 20 point average for air flow and 3% velocity accuracy via low friction 2.83 In. D (72 mm) ball bearing vane wheel on 3.9 ft (120 cm) cable Comes complete with 9v battery, protective rubber holster, case and NIST Certificate

Designed and built for a wide range of applications including process and HVAC cooling towers, industrial and commercial boilers, reverse osmosis systems, pools and spas. The ExStik® II pH/conductivity meter combines a rugged flat surface pH electrode with an auto ranging highly accurate conductivity cell to precisely measure conductivity, TDS, salinity, pH and temperature. It delivers seven selectable units of measure: pH, µS, mS, ppm, ppt, mg/L and g/L. It also provides automatic temperature compensation, adjustable conductivity to TDS ratio (0.4 to 1.0) and a 0.5 salinity ratio. The ...
