LI-250A Specifications

Accuracy:

25 °C : Typically ± 0.4% of reading ± 3 counts on the least significant digit displayed (all ranges).
0 - 55 °C : Typically ± 0.6% of reading ± 3 counts on the least significant digit displayed (all ranges).

Range Selection : Autoranging (3 ranges).

Linearity : ± 0.05%.

Sensors : Designed for type "SA" sensors; type "SB" and "SL" sensors with BNC connectors are also compatible when calconnector or millivolt adapter are removed.

Sensor Calibration : Each sensor is supplied with a calibration multiplier. Calibration multipliers for two sensors can be stored in memory. Calibration multipliers are entered from the keypad.

Signal Averaging : Sensor output can be collected and displayed as a 15-second average (approximately 60 readings). Averages are retained on the display in HOLD mode.

Display : 4 1/2 digit LCD display. Updated every 0.5 seconds in Instantaneous mode.

Battery Life : 150 hours typical with continuous operation.

Power Requirement : One 9V Alkaline battery.

Operating Conditions : 0 to 55 °C, 0 to 95% RH (non-condensing).

Storage Conditions : -55 to 60 °C, 0 to 95% RH (non-condensing).

Size : 14 cm L × 7.7 cm W × 3.8 cm D (5.5" × 3" x1.5").

Weight : 0.26 kg (0.57 lbs).

Warranty : 1 year parts and labor.
