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 4-20 mA devices. |

The Tuff-Tools line of
calibrators is designed to give the technician laboratory grade accuracy
in a family of rugged, easy to use instruments.
The Tuff-Tools family consists of 3 Process Signal calibrators (mA,
Volts, Frequency), 2 Temperature calibrators (T/C, RTD) and a Pressure
calibrator available in several ranges (200" H 2 O, 30 PSI, 100 PSI).
Operation of these calibrators is made easy through the use of a sealed
membrane keypad with simple controls. The outputs are set through the
use of step and ramp keys which allows both large and small output
changes to be made with ease.
Each Unit Includes: Test leads, carrying case, 9V battery, NIST
Certificate, and instruction manual. |

This multi purpose
process loop tool offers high accuracy in an ultra-small, rugged
package. The MiniSource Process Calibrator has the ability to
calibrate or troubleshoot any 4 mA to 20 mA loop device.
A single pushbutton allows the user to select one of the 5
current outputs (4, 8, 12, 16 or 20 mA) which can drive up to
300 ohms, or act as a 2-wire simulator with an external loop
power supply of up to 30 VDC.
Each Unit Includes: 9 V battery, NIST Certificate, and
instruction manual. |
