CLIOQC Model V -
Audiomatica
The QCBOX Model 5 is a non-conventional unit designed to fulfil actual and future needs of an electro-acoustical analyzer like the CLIO system. It is USB linked to a PC and can be configured, with dedicated software controls, to assist frequency response and impedance measurements or to perform DC measurements. Using it for frequency response measurements acts as 50W power amplifier to drive the speaker or network under test while routing one-of-four inputs to the analyzer as well the current sensing output. The four inputs are able to provide a phantom power supply both for Audiomatica or general purpose microphones (0-24 V range, software controlled). Impedance measurements can be done either switching the D.U.T.’s load across the analyzer’s input or using a dedicated output, ISENSE, thus allowing impedance measurements in constant voltage mode as well voice coil current distortion analysis. An internal ADC measures the DC current into the voice coil. Thanks to an internal software controlled voltage generator the speaker can be driven with a superimposed DC voltage (±20V), allowing for measurements of large signal parameters. Two ADC converters with a ±2.5 V and ±5 V are available at inputs 3 and 4 to measure the displacement with a laser sensor or any other DC signal. A dedicated digital input handles an external foot pedal switch (or TTL signal) to be connected and triggers QC operations. A 6 bit output – 5 bit input TTL digital port is available to interface the QCBOX and driving software with external hardware (like turntables for example).The QCBOX Model 5 finds use both in laboratory for R&D applications and in production lines setups.

PCE Instruments
PCE Instruments’ temperature meter products are precise, portable, handheld devices ideal for professional, industrial, commercial and residential use. From contact temperature meter devices with probes to noncontact temperature meter devices using infrared or laser technology to measure temperature from a distance, PCE Instruments offers a wide range of accurate, reliable temperature meter products at an affordable price.Temperature is measured and recorded in many different applications. For example, HVAC technicians measure temperature to identify and address issues in heating or cooling systems, while quality control professionals in the food sector measure temperature to ensure the proper storage and preparation of everything from meat and produce to cheese and frozen foods. PCE Instruments carries a variety of temperature meter products, including temperature meter devices to measure different temperature ranges between -200 and 1767ºC / -328 ... 3212ºF; temperature meter devices that can indicate temperature in °C (Celsius), °K (Kelvin) and °F (Fahrenheit); and temperature meter devices that are water resistant. In addition, a number of thermal elements and type-K sensors are available for different temperature meter products.Each temperature meter comes factory calibrated to ensure accurate measurement. ISO-certified calibration, performed by one of our first-class calibration laboratory partners, may be obtained on most temperature meter models for an additional fee.A temperature meter is an instrument used to measure the temperature of beings or things. The most widely recognized temperature meter is a mercury thermometer used to measure the temperature of people. These thermometers consist of a graduated glass capillary with a pool of mercury in one end. However, there are many different types of temperature meters, such as digital thermometers that take temperature measurements on contact with an object or infrared temperature meters that take measurements at distance, without contact.
