Exceptional accuracy and high read rate with five digital voltmeter ranges from 200.00 mV to ±300.0 V and four digital ammeter ranges from ±2.0000 mA to ±5.000 A, all factory pre-calibrated. Shipped ready to run.

Five AC RMS voltmeter ranges to 200.00 mV to 600.0 V and four AC RMS ammeter ranges from 2.0000 mA to 5.000 A, all factory pre-calibrated. Shipped ready to run.

Sealed on all sides to IP-65 / NEMA-4. Includes 1/8 DIN panel cutout and three wire glands. Available as BOX2 with IPC splash-proof cover.

User-scalable for display to ±999,999 for 0-1 mA, 4-20 mA, or 0-10 V process signals requiring zero and span adjustment. Includes a voltage-to-frequency converter to totalize analog signals, for example to display volume from a 0-10V flow transducer. Includes a 5, 10, 24V transducer excitation output (user-selectable).

A high-sensitivity 5-digit meter for use with load cells, strain gauges and microvolt input signals where high accuracy and stability are required. Most sensitive full scale of ± 20 mV. Load cell operation allows 4- or 6-wire hookup and display in engineering units, such as lbs, kg or psi. Built-in excitation for up to four 350-ohm load cells in parallel.

Equipped with a DC or load cell signal conditione board, this Laureate offers special firmware for scale / weighing applications: two tare functions; count by 1, 2, 5, 10, 20, 50 or 100; auto-zero function; setpoint offset, and dummy right-hand zero for display to 999,990. Built-in excitation for up to four 350-ohm load cells in parallel.

High accuracy in one instrument for seven thermocouple types (J, K, T, E, N, S, R), each in one range. User-selectable thermocouple type, °C or °F, and 1° or 0.1° resolution. Pre-calibrated for all sensor types. Wide range of options for communication and temperature control. Shipped ready to run.

Exceptional accuracy RTD temperature meter for Pt100 100-ohm platinum RTDs (DIN or ANSI alpha), Ni120 nickel and Cu10 copper. User selectable RTD type, unit of measure (°F or °C) resolution (1° , 0.1° or 0.01°), and 2, 3 or 4-wire hookup to eliminate lead resistance effects. Pre-calibrated for all RTD types. Wide range of options for communication and temperature control. Shipped ready to run.

Factory calibrated for five jumper selectable resistance ranges from 20Ω to 200 KΩ. Exceptional accuracy of ±0.01% of full scale. In the 20Ω range, resolution is 1 milliohm, making the meter suitable for contact resistance measurements. Custom curve linearizatio for transducers whose output is a changing resistance. 3 or 4 wire connection eliminates lead resistance effects.

All capabilities of the Laureate process meter, plus custom curve linearization. Setup is easy using an external PC and linearizing software furnished by Laurel. For example, display liquid volume in irregularly shaped tanks, use with non-linear transducers, or extend the working range of nominally linear transducers.

Universal meter for 65 user-selectable analog input signal types and ranges: DC voltage and current, AC RMS voltage and current, process signals (4-20 mA, 0-10V), thermocouple (10 types, °C or °F), RTD (6 types, °C or °F), thermistors (NTC or PTC), resistance (0-10k or 0-100k ohms), and potentiometer inputs. Universal 18-265 Vac/dc power. 1/8 DIN case.

Fits 22.5 x 45 mm cutout. Accepts 4-20 mA, 0-10 mA, 0-2 V, 1-5 V, or 0-10 V signals. Powered by isolated 10-30 Vdc.
