24/7 Technical Support

Monitoring radiation and EMF (Electromagnetic Fields) is vital to protect workers from the threats that they pose. Obtaining accurate exposure measurements is very important; understanding the level of radiation at a specific site is the first step towards the long term goal of reducing exposure to radiation. Pine supplies highly accurate radiation survey meters designed for measuring the complex electromagnetic field emissions from computers, video display terminals and any CRT or similar devices within the office.

Alpha Lab Vector/Magnitude Gaussmeter
Alpha Lab Vector/Magnitude Gaussmeter

The Vector Gaussmeter displays the true magnitude of the field at any location as well as the X, Y, Z components of up to 800 gauss. Also separately displays peak values of X, Y, Z, and magnitude. There is a sound alarm that determines the locations where the field magnitude exceeds user-set threshold. Because magnitude is measured, the orientation of the sensor (E-W, N-S, and up-down) is not important; this is unlike a 1-axis gaussmeter. With the VGM the user can set the alarm to 15 gauss (for example) and it will sound (simultaneous with a red light) whenever the field exceeds 15 gauss for at least 5 milliseconds. Using the meter this way, it is easy to make a map of the 15 gauss line (or for whatever threshold is set) around a strong magnet. When using the alarm, of a steel part can be rapidly scanned to show if any areas exceed the set threshold. Then the “peak hold” function can be interrogated, showing the peak values of X, Y, Z (including polarity) and magnitude that occurred during the scan. Peak hold also has a 5 millisecond response time. The “reset” button resets all peak hold registers to the present values of X, Y, Z and magnitude, which are displayed in real time when the knob is set to “measure.” Offsets can be manually applied to X, Y, and Z, or a “relative zero” can be applied to all three. This subtracts out the field at the time the button was pressed.

AlphaLab DC Milligauss Meter 3 Axis
AlphaLab DC Milligauss Meter 3 Axis

An improvement on the flux gate magnetometer, the AlphaLab DC Milligauss Meter measures magnetic fields (technically “flux density”) up to several times the strength of the Earth field. It has a resolution of 0.01 milligauss (1 nanotesla) and a range of +/-2000 milligauss (200 microteslas). The meter's three magnetoresistive sensors are a major improvement over an uncompensated fluxgate magnetometer both in cost and stability. In fact, the sensors approach a proton precession magnetometer in temperature stability.

Each of the three displays has an extra digit compared with most portable magnetometers. Each is 4 ½ digits and displays in two ranges: +/- 1999.9 and +/- 199.99 milligauss. Update is three per second. Because the Earth's field is typically about 500 milligauss, nine “offset” controls (three for each of X,Y,Z) allow you to add or subtract up to 600 milligauss with precision of .01 milligauss. Therefore, the Earth's field can be subtracted out when required. If reading in the more sensitive 199.99 range, this field neutralization feature is often necessary, because the field is usually stronger than 200 milligauss.

The wide dynamic range of the displays (19,999 count; both polarities), along with the large range of offset (+/- 600 milligauss) and high stability of the meter (+/- .01 milligauss), allow for stable detection of small changes in a large background field. On the higher sensitivity range, changes of .01 milligauss can be reproducibly measured in up to +/- 800 milligauss of background field. On the lower sensitivity range, absolute field of .1 milligauss can be measured in up to +/- 1999.9 milligauss of background field.

The sensor is a 25 mm (one inch) cube at the end of cable that is normally four feet long, but other custom lengths are available. Each axis reads negative when pointing toward the south pole of a magnet and positive toward north.

At fixed temperature, reproducibility is +/- 0.01 milligauss (1 nT) and the temperature coefficient of the offset is less than 0.01 milligauss/°C. The temperature coefficient for gain is less than .0015%/°C. As shipped, gain accuracy is +/-0.5% and the meter offset is +/- 0.5 milligauss with all offset knobs set at zero. All specifications are at temperatures 0 to 45°C. X,Y,Z are aligned with the cube edges to accuracy one degree unless you specify 1/10 degree in the drop-down box below.

MGM3AXIS Output Jack Description:
The outputs are an analog voltage, with 1 Volt = 1 Gauss +/- 0.5%. Range is +/- 2 gauss (= +/- 2V). Normally, it is a "slow-moving" DC voltage (valid DC to 3 Hz), but a higher bandwidth can be specified (DC to 300 Hz at the 3 dB point) at no extra cost. The X, Y and Z outputs each has a separate BNC output with a single common ground.

Narda THM1176 Magnetometer
Narda THM1176 Magnetometer

The Three-axis Hall Magnetometer is used to measure the magnetic field (flux density). Its unique, extraordinarily compact design allows it to be used as a portable instrument or directly connected to a PC.

The total magnetic flux density is provided no matter the orientation of the probe, which greatly facilitates many measurement tasks such as field mapping. Outstanding features are as follows:

  • Three axes
    Simultaneous measurTHMement of all three axes of the magnetic field provides the total field, no matter the orientation of the probe.
  • Microscopic field sensitive volume
    The High Field sensor volume of only 150 x 150 x 10 µm3 provides excellent localization and a self-consistent measurement of the three axes even in highly inhomogeneous fields. The Low Field sensor volume is 6 x 3.4 x 10 mm³.
  • Magnetic fields up to 20 T
    The High Field probe allows measuring even very strong fields as far as 20 Tesla. The standard calibration covers the range up to 3 T. The Low Field probe measures up to 8 mT with a resolution of 2 µT.
  • Bandwidth of DC to 1 kHz
    The 1 kHz bandwidth allows measuring AC fields generated, for example, by transformers and motors.
  • Graphical results display
    Magnetic flux density vs. time can be displayed as a graph. Measurement data can also be recorded to file.
