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.

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.

The PMBL is a 2 channel passive line level merge box. Each channel has 2 balanced XLR/f inputs. The input signal is merged via a resistor network to a XLR/m output.The top side input is transformer isolated. Possible applications might be the routing of two mixing desks to one power amp or mixing a stereo signal down to mono. Our transformer technology allows for an unbalanced top side input to be sent out balanced.
Specifications:
Each Channel: Input 1 transformer balanced XLR/f. Symmetrically decoupled through resistors
Total ohmic value: 2 K Maximum level for THD
Tests XLR, 1/4 in., 1/8 in., TT, RCA and MIDI connectors.
The intelligent, CPU-controlled CT100 accepts virtually any connector type:
XLR, mono and TRS phone (1/4 in., 1/8 in., TT), RCA and MIDI. It shows
which input pin is connected to which output pin. Separate LEDs indicate
proper shield connection and phantom power presence. The CT100 also
offers an installed cable test mode and a continuity check plus a test tone
generator.
Features
3 modes: cable test mode, installed cable test mode, and test tone mode
Accepts XLR, mono and stereo TRS phone (1/4 in., 1/8 in., TT),
RCA and MIDI Connectors
Continuity check
Intermittent detect
Phantom power detect
Grounded shield detect
Test tone generation (1 kHz and 440 Hz)
Battery operation (requires 2 AA alkaline batteries)
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.
