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.

Cable Tester ACT-100
The Alphaton active remote cable tester can be used for testing either normal short cables or long ones, especially mufticores, wkh connectors not being accessible at one time. The tester is especially suded for fixed installations where cables can not be tested with a standard type cable tester or Ohm meter. Either symmetric and unsymmetric cables can be tested. “Cold" solderings and junction resistances are displayed by color or luminosity changes in three color LED Display. The imprinted fault table incorporates alt important fault conditions, indeed not all possible ones due to their reiatively large number. In case the display is in a state which cannot be found on the imprinted table, it can be looked up in the user's manual. In any case, however, the cabie is in aquite unusable state and should be repaired or replaced.The Alphaton cable tester has a SEND and a REMOTE section. The REMOTE sectionconsistsof two recessed mounted XLR type male or female connector and a stereo phone jack at the right hand side of the tester. Additionally, a separate REMOTE plug is delivered togetherwith the active remote cable tester for testing long cables in fixed installations.
This is an on-the-road tool you certainly can't miss in your gearbox! A nifty, handy cabletester, which allows you to check up to six (welding) connections and gives you a visual readout by 2 rows of 6 LED's. The checking itself is done manually per connected pin. A LED will light up to indicate what pin is connected correctly on which side. A short-circuit check with a red LED and audio-warningsignal is also included. On the left and right side you'll find inputs for 6,3 symm. jack, BNC, RCA, 5p. DIN, 5p. XLR, 3p. XLR and Neutrik® Speakon®.
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.

User's ManualA stage is only as good as its cables — and the AHMCT 8 sets the record straight.
The AHMCT 8 tests the most critical cables on the stage itself and flags up whether they are functioning or not, both visibly via LEDs and audibly via a buzzer. This makes it the perfect tool for engineers — both in the workshop and on stage.
The Pro AHMCT is operated simply, intuitively and safely via a single rotary switch on the device. The sturdy metal housing withstands even tough on-stage demands.
The standard kit comes with two test probes for carrying out fast and simple continuity tests on various cables or installations.
