well as in the laboratory.
An alarm time-out is available to alert the user if too much time has
elapsed since the last pH calibration and that re-calibration may be
required.
The meter provides a controlled access to calibration and GLP settings
through a password protection method.
The Battery Error Preventing System (BEPS) recognizes batteries levels
as they become weak.
To prolong battery life, the backlight feature is automatically disabled
when the batteries are getting low; a clear indication is displayed on
LCD to warn the user of this condition. However, the meter continues
to measure correctly even when the low battery indication is dis-
played. The meter automatically switches itself off when the batteries
are too weak to support proper function.
For long term field and lab applications, these meters can be connected
to a 12VDC adapter.
The meters can store measurements in memory at the request of the
user for retrieval at a later time.
HI98140 and HI98150 also allow transfer of data to computer
through the RS232 port.
In addition, the meters allow the user to enter an ID code to uniquely
identify the instruments.
Made of tough, lightweight ABS material, the water-resistant rugged
casing is built to last.
The meters are in compliance with IP67 standards: dust-tight,
protected against the effects of temporary immersion in water and
designed to provide laboratory results and accuracy under harsh
industrial conditions.
