Sper Scientific products

Handheld Hot Wire Anemometer is a compact, accurate and robust device for measuring air velocity, volume, flow and temperature. Telescopic hot wire probe is designed to minimize the turbulence effect for in-duct measurements, and is well suited for low-flow applications. The probe features a rubberized ergonomic grip and extends/retracts from 10 to 38 inches. Timed and multi-point average flow calculations and in-duct air balancing with fast response time are enabled thanks to the depth and direction indicators.

Wirelessly log, display and transfer airspeed and temperature readings to your phone via Bluetooth. Sper Scientific’s Bluetooth® Anemometer Meter is small, light, and simple to use. Simultaneously displays air temperature in °C or °F, and air velocity in 5 units of measure, on the meter’s large 1-½” high backlit display. Features minimum and maximum hold (peak), data hold and moving average functions.

Light weight, tiny size with simple, one-hand, operation. They are perfect for scientists, agricultural specialist, facilities managers, HVAC professionals, home inspectors, field technicians, health and safety personal, hazmat crews, outdoor enthusiasts, educators, and coaches … all of whom need accurate information to properly access environmental conditions and make crucial decisions.

This unique instrument combines the features of an anemometer and a psychrometer. Measures air speed, air volume, BTU (British Thermal Units), air temperature, dew point, wet bulb and humidity. Excellent for HVAC, IAQ and environmental work. Auto ranging with air velocity in m/s or ft/s, air volume in CFM or m3/sec and temperature in °C or °F. Features min/max/avg, hold, auto power off, LCD backlight and a computer interface. The probe detaches for easy replacement and repair.

For environmental testing anywhere. Combines an anemometer, hygrometer, thermometer, and a light meter into a single compact unit weighing only 5.3 oz (150 g). Features dual display with low battery and over range indications, touch-tone buttons, min/max, auto power off and hold functions. Comes ready to use with soft carrying case, wrist strap, instructions, and a 9V battery.

This EMF meter measures electromagnetic field radiation, electric field and ambient temperature. It has multiple functions including: data hold & temperature measurement (?/? switch), testing average or peak value (Maximum) reading, safe/harmful warning, sound-light alarm, color LCD back-light, manual/auto shut off, battery indication. This EMF tester helps you eliminate the radiation risks that surround you and your family.

Measures electro magnetic field emissions from electrical power lines and transmission equipment, computer, HVAC, audio/video, and other electrical appliances and equipment. While the evidence of the carcinogenic effect of such electromagnetic emissions is still inconclusive, prudent avoidance is recommended to avoid excess exposure over long periods of time.

Simply approach the source at any angle and the triple-axis meter automatically determines EMF (electro magnetic frequencies), eliminating the need for additional calculations. X, Y, and Z axis results can also be viewed independently. Measures electro magnetic fields of extremely low frequency (ELF) from electrical power lines and transmission equipment, appliances, computer, HVAC, audio/video, and other electrical equipment. While the evidence of the carcinogenic effect of electromagnetic emissions is still inconclusive, prudent avoidance is recommended to avoid excess exposure over long periods of time.

Measure the RF strength of Wi-Fi and LAN, cell phone, radio and TV transmission towers, wireless cameras and microphones. Sper Scientific`s 3-Axis RF Meter 840047 measures RF (Radio Frequency) electromagnetic field strength in the frequency range of 50 MHz to 3.5 GHz. The 3-Axis probe provides simple, accurate, non-directional measurement from any angle. Results are displayed in large digits and a bar graph on a backlit LCD that also indicates maximum or average readings, low battery, and overload. You may set audible alarms a CAL (calibration) factor for a specific frequency or save and review up to 200 readings directly on the meter. Auto-ranging, with auto power off. Comes ready to use in a soft carrying case with belt loop, instruction manual and one 9V battery.
