Description
Overview
GAOTek Digital manometer with USB interface measures pressure up to 10PSI with built-in low range and high range error indicator.
Key Features
- Standard portable dissolved oxygen meter is equipped with a large backlit LCD display.
- 1 or 2 points calibration using the air-saturated water and zero oxygen solution.
- Manual salinity and barometric pressure compensation improve the measurement accuracy.
- Automatic Temperature Compensation ensures accurate reading over the entire range.
- Calibration Due Reminder prompts user to calibrate the meter regularly.
- Stability indicator automatically shows current measurement status.
- Auto-Hold function freezes stable measured value for easy viewing and recording.
- Manual temperature calibration improves the measurement accuracy of meter.
- Selectable temperature unit (°C or °F) meets different application requirements.
- Help message as a operational guide that helps you quickly begin using the meter.
- System menu allows setting the 9 parameters, including the number of calibration points,
resolution, stability condition, concentration unit, etc. - Reset feature automatically resumes all parameters back to factory default settings.
- Expanded memory stores and recalls up to 500 readings.
- Built-in real-time clock stamps stored data to meet GLP standard.
- Stored data can be transferred into computer by USB communication interface.
