The MiniSPL is the perfect accessory to the Acoustilyzer & Minilyzer for
acoustical measurements.
The MiniSPL is a battery powered measurement microphone. Together
with the Acoustilyzer or Minilyzer, it forms an acoustical analyzer and integrating
sound level meter. Additionally it may be operated as a stand-alone microphone
e.g. connected to a balanced audio-line, a microphone-input or a sound-card.

| Non-Contact Laser Thermometer LCD Digital IR Infrared Thermometer GM400 Temperature Meter Gun Point -50~400 Degree
This infrared thermometer USES non-contact infrared sensing technology, the target of safety, preparation, fast, reliable measurement, is widely used in measuring the mechanical, chemical, ceramics, light industry, food, metallurgy, electric power, high temperature heat treatment and other industries, dangerous and difficult to close to the surface temperature measurement. Temperature measurement is widely used in the school laboratory and home.
Objects of any temperature greater than absolute zero radiation infrared energy, this energy to around at the speed of light transmission, infrared lens collects and gathers the infrared energy to the sensor, the sensor produces a low output voltage, the voltage is proportional to the temperature of the target object, voltage after processing for the temperature value.
- Not recommended for human use.
