The UL-listed Laureate Dual-Channel Pulse Totalizer provides two channels, A&B, which may be independently scaled to count up from zero (or other value) to a preset limit, or count down from a preset value to zero (or other limit). Scaling allows direct readout in engineering units, such as gallons, based on counts from a turbine flow meter. Totals are stored in non-volatile memory. (read more)

The Laureate Model FRR can apply arithmetic functions (+, -, /, x) to two independently scalable pulse input channels, A and B. It can add two flows (A+B) for total flow, subtract two flows (A-B) for net flow, take the ratio of two rates (A/B) to control mixing, or compute draw (A/B-1) to display net elongation of material between rollers. Pulse rates can be from 0.05 Hz to 1 MHz. (read more)

The 88-PRO Process Meter may be connected directly to a 4-20 mA, 10-50 mA or 1-5 mA current loop, with no need for additional power. This is because the meter is powered directly by the current loop, developing a maximum voltage drop of 2.5 V. It fits in a standard 1/8 DIN panel meter cutout and is only 93 mm (3.66") deep. There are only two signal connections: signal in, signal out. (read more)

The Laureate Model SG is UL-listed 5-digit digital panel meter for strain gauges and process signals. Strain gauges with a 20 mV output can be scaled to display up to 10,000 counts, while a 200 mV output can be scaled to 99,999 counts to read directly in engineering units, such as Lbs. Accuracy is an exceptional 0.01% of full scale ± 1 count. The meter read rate can be up to 60/second. (read more)

The Laureate Model P is a UL-listed 5-digit panel meter for process signals such as 4-20 mA, 0-5 V or 0-10 V, which require zero and span adjustment. It can be scaled to five full digits from the front panel to read in engineering units, such as PSI or GPM. Accuracy is 0.01% of full scale ± 1 count. An adaptive digital filter provides stable readings in electrically noisy environments. (read more)

The Laureate Model WM Load Cell and Microvolt Meter is a UL-listed, high-sensitivity digital readout and controller for load cells, strain gauges and microvolt signals where high accuracy and stability are required. The unit combines exceptional accuracy of 0.01% of full scale with rates up to 60/sec. Such high read rates are ideal for peak capture, alarm, control, and computer interface. (read more)

Model BAR Bargraph Meter provides a graphical display of analog process signals, such as 4-20 mA, 0-20 mA, 0-10 mA, 1-5 V or 0-10 V. The bargraph consists of 30 LED elements. These can be red or green and be set up with a moving dot for position monitoring, or in the traditional accumulating bar format. The case is 1/8 DIN size as for most digital panel meters, and fits in the same cutout. (read more)

The Laureate Model VF is a UL-listed, programmable 6-digit panel meter which can display rate or totalized rate from transducers with a 4-20 mA, 0-1 mA or 0-10V output. Readings can be scaled to engineering units such as gallons per minute or gallons. Square root extraction is standard for use with differential pressure flow sensors and is applicable to rate or total. (read more)

The Laureate Model RMS is a UL-listed, 4-1/2 digit, true RMS panel meter which provides 0.15% ± 1 count accuracy for AC voltage or current signals from 10 Hz to 10 kHz. It is suited for AC applications where there is considerable distortion of current waveforms from nonlinear loading. The input is AC coupled to read only the AC component, such as ripple on a power supply. (read more)

The Laureate Model DC Digital Voltmeter & Ammeter is a UL-listed, 5-digit panel meter with 0.01% full-scale accuracy and read rates up to 60/sec. Such high read rates are ideal for peak capture, alarm and control, and real-time computer interface. The Laureate DC is ideal for use with external current shunts, which typically produce 50 mV or 100 mV at their rated maximum current. (read more)

The Laureate Model FRT is a UL-listed, 6-digit panel meter which can simultaneously track rate and totalized rate from the same pulse input. The display can be toggled between rate and total at the push of front panel key or external switch. When used with a turbine flow meter, the unit can display rate in units of flow, such as GPM, or totalized flow in units of volume, such as Gallons. (read more)

The Laureate Model T is a UL-listed temperature meter/controller for highly accurate, stable and repeatable temperature indication with multiple thermocouple types and 100 Ohm platinum RTDs. The meter accepts types J, K, T, E, N, R and S thermocouples plus 100 ohm platinum RTD's with DIN or ANSI alpha. The thermocouple or RTD type, range and resolution (1° or 0.1°) are user selectable.

The Laureate Model LW is a UL-listed, 5-digit panel meter with special firmware for weighing applications. The unit provides a choice of two signal conditioner boards: a load cell signal conditioner with full-scale ranges down to 20 mV, and a DC signal conditioner for preconditioned signals such as 0-10V or 4-20 mA. With either signal conditioner, accuracy is ±0.01% of full scale ±1 count. (read more)

Grand Series Large Digit Displays provide oversize digits for long viewing distances indoors or outdoors up to 300 ft (90 m). A rule of thumb is that viewing distance in feet is 40 times digit height in inches, or viewing distance in meters is digit height in millimeters divided by 2. Four digit heights are available: 57 mm (2.2"), 102 mm (4.0"), 144 mm (5.7"), and 200 mm (7.9"). (read more)

DIN Rail mounted, digitally programmable.

Datalogging Software by Laurel Electronics can turn a PC connected to up to 32 digital panel meters, counters and timers into a powerful datalogging system with distributed displays. On-screen simulated meters can show readings and alarm indications of actual meters or mathematical combinations of readings. Data can be saved in an ASCII file and imported into MS Excel for graphing and analysis. (read more)

Custom Curve Linearization is a feature available with the Extended version of all Laureate digital panel meters and counters, excluding only temperature meters. It can provide exceptional accuracy from low-cost transducers, extend the working range of transducers, and solve special application problems where there is a non-linear relationship between the input and the desired reading.
