Field Strength Meters
The FSM series of field strength meters will measure the strength of a RF signal appearing at its input from +20 dBm to -110 dBm for wide bandwidth models and +10 dBm to -120 dBm for narrow bandwidth models. The RF strength will be displayed on an LCD display to an accuracy of ±3 dB over the entire 130 dB dynamic range.

Field Strength Meters
FIM-22 And FIM-41
The Models FIM-22 and FIM-41 are portable field strength meters designed to provide precise, direct measurements of electro-magnetic fields in the 200 kHz to 5.0 MHz spectrum. These units include a receiver, integral shielded loop antenna, precision attenuator, internal calibration source, and battery power supply. With calibration accuracy traceable to the National Institute of Standards and Technology, the FIM-22 and FIM-41 meet the most exacting requirements of government and industry. Their hinged covers, on the rugged drawn aluminum cases, contain a loop antenna. Opening the cover to a vertical position connects the antenna terminals to the receiver via maintenance-free gold-plated contacts. An interlock switch prevents inadvertent battery discharge when the cover is closed.

Magnetic Field Meter
MP - 2000
The new magnetic field meter MP - 2000 first used probes (tangential and Axialfeldsonden), in which an own microcontroller, the analog sensor signals are digitized and linearized directly in the probe. This new technique is extremely trouble-free and allows very precise measurements, especially at high magnetic field strengths, where Hall probes can not operate linearly.

This meter measures AC electric field in the vertical direction (same direction as the long axis of the meter). It has a wide frequency range (40 Hz - 20 KHz) and high accuracy (+/-2% of reading +/- 1 count) with an electric field strength range of 19 999 V/m and resolution of 1 V/m. The sensor is in the top 1/3 of the meter.

Electrical Constant fields
Electrical DC fields are created by friction between different materials. Synthetics in particular result in unnaturally high charges, which lead to stress reactions such as in a thunderstorm. The electric field strength is measured in volts per meter (V/m) or the surface tension in volts (V).

RF Proximity Detector
Type RPD-2 AND Type RPD-2A
The Type RPD-2 Radio Frequency (RF) Proximity Detector is designed to detect and locate devices that radiate radio waves in the high frequency to low microwave frequency range. Such devices often include surveillance and “spy” equipment. The Type RPD-2, when used with the different sensors, will detect the emanation of the radio wave within a confined area, and then isolate its location to within approximately a square foot. The type RPD-2A may be used as an RF field strength indicator for antenna field strength measurements. The RPD-2A is identical in function except that the meter scale is calibrated in relative dB units.

Radiation (EMF, Nuclear, RF)
Sper Scientific radiation meters measure EMF, Nuclear, and Microwave radiation levels. Whether you are, measuring the RF strength of Wi-Fi and LAN network, or the electromagnetic field emissions from electrical power lines and transmission equipment, computers, HVAC, audio/video, and other electrical appliances. Our meters are small and light enough to go anywhere, yet sensitive enough to detect minuscule amounts of gamma, beta or X-rays.

Current Caliper
KH23101
Beijing KeHuan Century EMC Technology Co,.LTD
The KH23101 current caliper is a toroidal transformer used to measure EMI current. When measuring, the caliper does not directly touch the electrical conductor or the cable under test. The conductor passing through the caliper window is used as the single-turn primary wire of the transformer, and the secondary is designed to be multi-turn. Use with 50 Ω receiving system (such as EMI electromagnetic interference field strength meter or spectrum analyzer). In order to facilitate installation and rapid measurement of EMI current, it is designed as a caliper that can be opened.

DC Gaussmeter
GM1-HS
The Model GM1-HS measures the strength and polarity of magnetic fields up to 799.99 gauss. The thin sensor is at the end of a 100 cm flexible cable. The sensor tip is also flexible and can be bent for a variety of situations. The sensor can be held against the surface of a steel part to check for residual magnetism, or it can be bent into an "L" shape to measure inside a DC Solenoid. This meter has a resolution of .01 gauss (1/50 of the Earth's typical field) which is finer resolution than the Model GM1-ST. It is also used to map fields from large magnets (If fields are over 800 gauss, use the Model GM1-ST). The meter has immediate turn-on and updates 4 times a second. There is no setup required, making this the fastest gaussmeter available.

DC Gaussmeter
GM1-ST
The Model 1-ST measures strength and polarity of magnetic fields up to 19,999.9 gauss. The sensor can easily fit in a .060 inch (1.5 mm) gap and is at the end of a 100 cm flexible cable. The sensor end can be bent if required for a variety of situations. Place the sensor on a magnet face to measure the field. With a resolution of 0.1 gauss, it can measure any tiny variation from magnet to magnet or it can detect if a given magnet has lost even a little strength. Bend the sensor in to a "L" to measure inside a DC solenoid tube. The 5 digit display requires neither auto nor manual range change, making it easier to use than older style 3 or 4 digit meters. Turn on the meter and immediately begin reading fields (updates 4 times per second). There is no setup required, making this the fastest, easiest gaussmeter available.
