NewportQ2000-JDF11/8 DIN Digital Panel Meter, Type J Thermocouple Temperature Indicator, Red LED, 115 VAC

Product Description

What this part is

This is one Newport QUANTA Q2000-series digital panel meter configured as a Type J thermocouple temperature indicator. It is a complete panel instrument in a 1/8 DIN polycarbonate case with a red LED display: you wire a Type J thermocouple to the rear terminals and it reads temperature directly, with cold-junction compensation and zero and span trimming built in. It is an indicator, not a controller card and not a transmitter — it displays and, on relay-equipped variants, switches; it does not run a control loop from a program.

Decoding the order code

Q2000 — the QUANTA Q2000 family: 1/8 DIN panel-mount digital meter, polycarbonate case, red LED display, screw-terminal rear connection. Panel cutout follows the 1/8 DIN standard (44.96 mm high).
J — the input: Type J thermocouple, iron / constantan. This is the field that decides fit — a Type J meter will read a Type K probe, but it will read it wrong, because the linearisation curve and the cold-junction compensation are burned in for Type J.
DF1 — the Newport display, range and output option group for this build, followed by the power/option digit. Newport built the Q2000 to order from this suffix, so two meters that both read Type J can still differ in decimal placement, engineering-unit scaling and whether setpoint relays are fitted.

What these specs mean in practice

Type J tops out lower than Type K and drifts if it is run oxidising at high temperature, so it lives on plastics extrusion, ovens, dryers, platens and older process skids — exactly the machines where a dead panel meter stops production even though nothing mechanical is wrong. Because this is a line-powered 1/8 DIN meter, it drops straight into an existing cutout and reuses the existing thermocouple wiring; there is no signal conditioner or loop supply to add.

Published specifications

Input: Type J thermocouple, iron/constantan, with cold-junction compensation
Display: red LED numeric, front-panel readable
Supply: 115 VAC line power, approximately 7 W
Case: polycarbonate, 1/8 DIN panel-mount, rear screw terminals
Adjustment: zero and span trims for readout in engineering units

Quantity and configuration

Sold as one meter. No thermocouple probe, no extension wire, no panel gasket or mounting clips, no manual and no protective cover are included. Use Type J extension wire (white/red under ANSI colour code) all the way back to the terminals — splicing copper into a thermocouple run creates a second junction and a reading error that looks like a faulty meter.

Installation and setup notes

Isolate the panel before wiring: the rear terminals carry 115 V line voltage alongside millivolt-level thermocouple inputs, and that is exactly why the thermocouple pair must be run as a twisted, screened pair away from contactor and drive wiring. Observe polarity on the thermocouple — reversed leads give a reading that falls as the process heats. After fitting, confirm the reading against a calibrator or an ice bath before trusting it for a process alarm.

Interchange guidance

Searched as Q2000-JDF1, Q2000JDF1, Q2000 JDF1, Q-2000-JDF1 and Newport QUANTA Q2000. Newport Electronics is now part of Omega Engineering, so this instrument is also catalogued under Omega, and the Q9000-series QUANTA meters are the same platform in other case and power configurations. Sister builds worth searching if the suffix does not matter to you: Q2000-KDF1 (same meter, Type K input) and Q2000-JDC1 — both are dimensionally identical 1/8 DIN QUANTA meters, but the input type or the option group differs, so confirm the letter after Q2000 against your thermocouple. Newport’s later replacements are the INFINITY / iSeries and DP-series panel meters, which need the same 1/8 DIN cutout.
