The new Additel 209 and 210 loop calibrator series combines ease of use and functionality, making them the ideal tools to troubleshoot your process loop. The ADT209 has an accuracy of 0.03% of reading and the ADT210 holds an accuracy of 0.01% of reading. If you want to source, simulate or simply measure, the Additel Loop calibrator series will fit your needs. The ADT209 and ADT210 allows for measurement of current, voltage and a switch. You can also simulate or source mA or a process transmitter. With the push of a button, you can switch to zero and span values, auto ramp, and auto step throughout the range. Each loop calibrator has a large, easy to read screen which simultaneously displays the measurement with the % of span.
The ADT 220 multifunction loop calibrator is a compact, rugged and easy to use hand held device for sourcing, simulating and measuring mA, mV & V, checking loop integrity and capture switches. The ADT 220 is ideal for calibrating and maintaining various loop devices on site.
The Martel LC-110 series of mA (loop) calibrators are designed to take the loop calibrator class to the next level. The new LC-110 features a user friendly interface with dedicated buttons and a rotary encoder (Quick-Set Knob). This combination drastically reduces the time it takes to measure, simulate, or source both voltage and current and power up a loop.
The new LC-110H not only has all the features from the standard LC-110 but it also incorporates HART communications and supports a select set of the HART universal and common practice commands. This unique feature allows the LC-110H to be used as both a loop calibrator and communication tool.
The PSC-4010 is a superior Process Signal Calibrator with voltage, current and frequency functions. With the best display in the business it makes the essentials of instrument calibration easier than ever. This Process Signal Calibrator is a portable, handheld, full function voltage, current, and frequency device with the capability to both read and source common process control signals.
The Martel Electronics LC-100 Precision Loop Calibrator provides significantly extended performance when compared to any competitive calibrator. With an accuracy of 0.015% of reading, with 0.001 mA resolution, the LC-100 has the highest accuracy in its class. Unique features, such as a “% Error” function, which eliminates manual error calculation and allows the display of the actual versus ideal error at any calibration point, put the LC-100 way beyond similar instruments. The Martel LC-100 can simulate, power, and measure two-wire transmitters. With automatic Step and Ramp functions, the LC-100 enables remote calibration of 4-20mA devices.
The Martel Electronics IVC-222HPII Voltage/Current Calibrator is a general purpose current and voltage source that can be used in engineering, manufacturing, test, and process control application. It combines both digital and analog circuitry to achieve its rated specifications in a small, reliable package.
The IVC-222HPII has the capability to store and recall up to two set-point values, the SP1 and SP2 keys. An RS-232 port accessed via a custom cable (available from Martel) allows the calibrator to be computer controlled for automated testing.
The Martel Electronics MS-420 Mini-Source Portable Calibrator is a multi-purpose process loop tool that offers high accuracy in an ultra-small, rugged package.
A single pushbutton selects one of five current outputs (4, 8, 12, 16 or 20 mA), which can drive up to 300 Ohms, or can act as a 2-wire simulator with an external loop power supply of up to 30 VDC.
Each unit is provided with a 9V battery, NIST Certificate, and instruction manual.
