A
Quality Australian-Made Meter |
|
|
_ |
The Australian made
TPS 90C is ideally suited to spot
checking and logging applications.
The sensors allow for in-situ measurements in
boreholes, lakes, streams, sewers and channels. With extended cable lengths
available up to 100m, the 90C is great for conductivity profiling.
The 90C measures:
- Conductivity
- Salinity
- Temperature
|
Easy to use and field rugged...
Easy-to-use with 80 character display:
Provides simultaneous viewing of all channels;
common-sense menu system; calibration prompts; and error messages.
Field rugged & waterproof: Designed for
field applications in wet environments. The case, keypad and connectors are water
resistant (IP65 rating).
|
Data Logging
The 90FL comes with standard and optional data logging:
Standard Data Logging: store the current
readings in memory (maximum 60 readings).
Extended Data Logging: increased memory,
calendar/clock and RS232 port, enables storage of 2880 timed readings. Can be set to sleep
mode between readings to conserve power. Readings can be downloaded to PC via included
DOS-based software (Windows version available).
Extra A/B Data Option: Allows the user to
type in data from other instruments and store with the 90FL readings. Ideal for adding
readings from instruments such as rainfall and turbidity monitors.

Sensor
Conductivity/Salinity/Temperature: pure
Platinum wide range (k=10) electrode for optimum accuracy and
stability over the wide range of Conductivity and
Salinity values found in the environment. The body of the sensor is moulded from
RYTON, a new space-age plastic developed for rugged applications. Also provides
temperature compensation to oxygen and pH readings. Standard cable length is 5m with
lengths up to 100m optional. Another
optional sensor with a sensitivity of k=1 is also available for
measurements of lower levels of Conductivity or Salinity. |

Good Laboratory Practices
Date, time and value of last calibration for each parameter are stored.
This information can be recalled or sent to the RS232 port at any time.
Warning of failed calibration is provided.
All readings stored in memory are stamped with the date and time.
Datalogging
2720 readings (2032 with extra data input active).
Extra Data Input
2 extra items of data can be input when using the Notepad function.
Each item can be a maximum of 4 characters, including a decimal point.
Extra Data items are labelled A and B.
Automatic Logging
The 90-C can be programmed to...
- Automatically log from 1 to 288
readings per day.
- Automatically log at up to 12
specific times of the day.
- Automatically log readings at a
preset interval for a preset
duration.
