Ametek MTC- 650 A Specifications

MTC- 650 A

Marine Temperature

Calibrator

Save Time, Save Money

Up to 3 Year Calibration Interval

Maximize accuracy with a one year recommended calibration interval, or lower your cost

of ownership by extending your interval up to three years! Reduce costs associated by

recalibration and managing assets by 66%.

Fast Calibration

The MTC-650 A contains an innovative heating block prole, which heats up to

650° C / 1202° F in only 18 minutes. The special heating prole minimizes mass and yet, still

accepts an insertion tube with a 1 in (26 mm) outer diameter. It’s the perfect compromise

between temperature stability, homogeneity, and rapid heating and cooling.

With wide temperature ranges from 28 to 650° C /

82 to 1202° F, the MTC-650 A portable temperature

calibrator facilitates correct readings on all of your

temperature monitoring devices.

Easy to Read, Intuitive Operation

The MTC-650 A temperature calibrator is simple to operate. Access to the most commonly

used functions, such as Set, Preset, Switch test and Auto step, is only one click away. An

easy-to-read and very informative color display oers a full overview of the calibration task

you are currently performing. The editable elds are marked in light blue. Navigating is

fast and easy using arrow keys and the enter key.

Multi-Information Display

Status Bar

Shows information about

recalibration due status and hot/

cold safety warnings and keeps

track of date and time.

Calibration Settings

Shows the actual calibration

settings for reference sensor and

stability criteria. Can be accessed

and changed directly in the

display by use of the arrow keys.

Calibration Status

Shows current status of the

calibrator, like heating/cooling,

stability achieved and expected

time to stability.

Function Bar

Shows the current possibilities of

the function keys.

Function Keys

The function keys serve as shortcuts to the main functions

like Set, Preset, Auto step and Switch test. When entering

one of the functions the function key shows the options

within the selected function.

Informative color display and
intuitive operation

The MTC-650 A is designed with an easy to read

and very informative color display that gives you a

full overview of the calibration task you currently

are performing.

Useful Features

Mains NormalMVI

The MTC-650 A is a very versatile calibrator with many integrated functions - you can run the calibration in four dierent ways.

Set function Preset mode

The fastest and simplest way of starting the calibrator.

Simply press SET and type in the wanted temperature

and o you go.

In Preset mode you just activate one of the preset

temperatures. Naturally the presets are programmable

for your specic needs.

MVI – Mains Power Variance

Immunity improves temperature
stability

major contributor to calibration inaccuracies.

Traditional temperature calibrators often become

unstable in industrial environments where large

electrical motors, heating elements, and other devices

are periodically cycled on and o. The cycling of supply

power can cause lower quality temperature regulators

to perform inconsistently, leading to both inaccurate

readings and unstable temperatures. The MTC-650 A

employ the MVI, thus avoiding such stability problems.

The MVI circuitry continuously monitors the supply

Unstable mains power supplies are a

Auto Switch Test Auto Stepping

Switch test calibration is a perfect time saver. Start the

switch calibration and come back to note the results

after the test. You decide if you want the deadband or

not - and the test can be repeated automatically in up to

three subsequent runs.

voltage and ensures a constant energy ow to the

heating elements.

In AUTOSTEP mode you can program as much as 12

temperature steps and at the same time set the dwell

time. Even the stability criteria can be programmed. Just

start the sequence and the calibrator will run through

the steps.

MTC-650 A Inserts

Use of other inserts may reduce performance of the calibrator. To
get the best results out of the calibrator, the insert dimensions,
tolerance and material is critical. We highly advise using Jofra
inserts, as they guarantee trouble free operation.
