Digital Indicators-Model 500-High Quality, Small Size, 1/8 DIN
The Model 500 is designed for a variety of temperature measuring applications. Excellent accuracy and its small size combine to make it the ideal choice for most industrial temperature indications.
The 500 features a unique 0.1° or 1° automatic resolution. For temperature measurements below 1000°, the instrument displays to a 0.1° resolution. Crossing over 1000°, the instrument automatically switches to a 1° resolution. Thermocouple types R, S and B only display in 1° increments. For any application where a 1° resolution is desired for everything, the unit can be set to display only 1° increments throughout its measuring range.
For ease of installation, each instrument is supplied in a standard 1/8 DIN (48 mm x 96 mm) plastic case and has rear-accessible universal screw terminals. Large LEDs make temperature readings easy to see and read, even from a distance. Power is derived from 115 or 230 VAC. Power is selectable via an internal slide switch.
Select between nine temperature sensors of thermocouple types J, K, T, E, R, S and B or 100 Ohm 3-wire, Platinum RTDs, either 0.00385 or 0.00392 alpha. Each of these nine are selected via a miniature rotary switch located directly behind the snap-off front lens. Another miniature DIP switch, also behind the lens, selects between °F or °C display.
Model 500 Options: The Model 500 accommodates one of two avaailable options. Either option can be specified at time of initial order or can be easily installed at some future date
Alarm Setpoint:
- The alarm option provides a single limit setpoint that can be set to any point, + or -, within the 500 measuring range. The user digitally sets the setpoint via two buttons located on the front panel.
- Selection of “HIGH” or “LOW” Alarm is set via a jump-jack located on the option card. Once the setpoint is set, it may be reviewed for its actual value by depressing the “view” button. A front panel LED illuminates when the alarm trips.
- The Alarm Setpoint option card also includes a Form C, 0.5A relay for hook-up to external lamps, buzzers or on/off control elements. Relay terminals are accessible at the rear of the instrument and provide hook-up for Normally Open or Normally Closed Operation.
Order Option: Model 500-ALM Multiple Inputs :
- The cost of measuring multiple temperature sensors can be cut using the 500’s ability to switch between up to six sensor inputs with its multi-input option. All input types contained in the 500 (thermocouple or RTD) can be switched, but they must all be of the same type (e.g., Type K Thermocouple).
- A miniature rotary switch, accessible at the front lens, allows convenient switching between inputs. Sensor hook-up is to a snap-on/off terminal block located at the rear of the instrument.
Order Option: Model 500-206 Model 500 Accessories:
- The Rack Adapter Plate permits easy mounting of Model 500 Indicators in standard 19″ instrument racks. Four versions are available for mounting 1, 2, 3 or 4 indicators.

HANDHELD CALIBRATOR/INDICATOR Model 845
The 845, the industry's price/performance leader, puts tab-quality calibration and high-performance thermometry in the palm of your hand. Providing 0.5°F accuracy for base metal thermocouple types and 1.7°F accuracy for high temperature thermocouple types and full range resolution of 0.1° in F and C, these instruments are superior for simulating and reading temperatures. Big, "One-Touch" keys let you quickly program every function for both calibrator and thermometer. Use the keypad to select TC types (up to 11 on some models). RTD and Ohms functions, calibrator or thermometer mode, 8F or °C, view 10 memory locations or hold the thermometer reading. The big, bright 5-digit LCD shows all active functions and there are no dials, switches or ramp keyboards to contend with. Calibrator set points can be programmed from an outside source through the thermometer memory mode or direct via the calculator-style keypad. A step function allows one touch output of programmed values, and when turned off, the units retain last-programmed values for quick repeat use. The thermometer mode provides accurate, dependable readings. Ten memory locations let you store temperature measurements for later review.
