Measuring with calipers
Overview

Our range of precision instruments for measuring length is manufactured by United Precision Machine, Inc (UPM®), a Chinese company with ISO9000/2000 QMC rating and CE. The company is specialised in the design and production of a large range of such instruments. UPM strive for highest accuracy, durability and overall quality at remarkably low prices. The company has introduced such innovations as 3 and 5 point calipers and holds many patents. It is our aim to keep most of these items in stock.

All of the instruments read in either metric or imperial and may be used for conversions.
A battery saving feature turns the display off after 4 minutes of non-use. When pressing "on" again to re-activate, the display returns to the original reading.
Also, a port is provided on calipers, and not micrometer screws for data transmission to a computer file or printer, via a special connector cable.

We offer a one year warranty on these instruments.

For some applications a measuring magnifier (magnifier with graduated reticule) may be most useful. Some reticules measure angles and screw-pitch too. We also supply measuring microscopes, please email us with your requirements.

DIGITAL CALIPERS, ABSOLUTE/ RELATIVE ZERO

After a particular reading is "zeroed" a subsequent measurement is shown as the difference. The zero function does not hold the reading in memory, as does the ABS/REL.
The first measurement when "ABS" is pressed is placed in memory. Then a second reading may be taken, which is shown as a difference. Press ABS again and the second setting is placed into memory, overwriting the previous reading.
Supplied in foam lined plastic box.

Functions: on/off, mm/inch selection, ABS and zero settings
Resolution: 0.01mm
Accuracy: ± 0.02 - 0.04mm

DATA TRANSMITTER FOR CALIPERS AND INDICATORS

This USB plugin device self-installs on the computer and recorded data may be filed or transferred to a data sheet. The control unit includes a slider on the side of the box to move the cell right, down or remain in the same location. Another slider selects precision between 0.01 and 0.001mm records the micrometer's reading and a beeper verifies success. The beeper may be disabled by a switch after opening the box' panel. A foot switch jack is provided if very many data points require recording.

DIGITAL MICROMETERS

Digital external micrometers with large display and data output. Supplied in a foam lined plastic box with calibrating bar and spanner for battery replacement. The calibrating bar can also be used for making smaller measurements.
After a particular reading is "zeroed" a subsequent measurement is shown as the difference. The zero function does not hold the reading in memory as does the R/A/REL. When a reading is placed in "hold" the measurement is retained even when the calipers are moved or when the calipers are switched off. Pressing "hold" again resumes normal functions.
The upper and lower tolerance may be set and while the reading is within the tolerance, "OK" is shown. Otherwise an up or down error indicates when the tolerance is exceeded.
The first measurement when "R/A" is pressed is placed in memory. Then a second reading may be taken, which is shown as a difference. Press R/A again and the second setting is placed into memory overwriting the previous reading.
Reset brings any reading to zero, however, when reset is held and the or - sign is also pressed any reading may be entered and this new value becomes the value of "reset". That new value may be zeroed by holding "reset" and pressing or - buttons until zero is reached. The /- buttons speed up when held.
The blue mm/inch conversion button functions as the "on" button. "Off" is automatic after 4 minutes of non-use, but pressing the conversion button restores the last setting.
A locking lever locks the micrometer screw.

SUM2-025 functions have been changed. They now include: ASB/inch/mm selection and OFF/ON/ZERO/SET.
