Perfect multiprobes for spot checking. Use with SVR4A®, NX8 and NX10 handheld displays.
Compact MS:
- Is only 17” long and 1.75" in diameter, which makes it very portable.
- Supports SDI-12 communication protocol. It will easily connect to a datalogger like Sutron®, Handar®, Waterlog®, or any datalogger that uses SDI-12.
- Supports RS232 communication protocol. It will easily connect to a PC or PDA.
Measures up to seven parameters simultaneously:
- Temperature in °C and °F,
- SpConductivity in µS/cm and mS/cm
- Salinity in ppt
- pH
- Dissolved Oxygen in % saturation and mg/l
- ORP (Redox) in mV
- Total dissolved gas “TDG” mmHg
Specs:

Optical Dissolved Oxygen sensor. Hach LDO sensor:
- Range: 0 to 20 mg/L
- Accuracy: +/- 0.1 up to 8 mg/L ; +/- 0.2 above 8 mg/L
- Resolution: 0.01 mg/L
The Conductivity sensor uses four graphite electrodes in an open cell design.
- Range: 0-100 mS/cm
- Accuracy: ± (0.5% of reading + 0.001 mS/cm)
- Resolution: 0.001
The pH sensor uses a glass bulb and refillable reference electrode.
The ORP sensor uses a simple platinum band that donates or accepts electrons
to monitor chemical reactions, quantify ion activity, or determine the oxidizing or reducing properties of a solution.
pH:
- Range: 0 to 14 pH units
- Accuracy: +/- 0.2 units
- Resolution: 0.01 units
ORP:
- Range: -999 to 999 mV
- Accuracy: +/- 20 mV
- Resolution: 1 mV
The Total Dissolved Gas (TDG) sensor uses a pressure transducer mounted behind a rigid gas-permeable silicone membrane to measure the amount of total gaseous compounds dissolved in a liquid. Maximum water depth is 25 m.
- Range: 400 – 1300 mmHg
- Accuracy: +/- 0.1% of span
- Resolution: 1.0 mmHg
Most common questions and answers:
Q: Does the Compact MS use the same communication protocol as the Minisonde®?
A: Yes. The Compact MS uses the same firmware as the Minisonde® with all its features.
Q: Does the compact MS replace the standard Minisonde®?
A: No. The compact MS is specialy design for spot checking and use with a datalogger.
Q: Can I use the Hydras 3 LT software to communicate with the Compact MS?
A: Yes.
Q: Can I use the Hydras 3L Pocket software with the Compact MS?
A: Yes.
Q: Can I use my existing Hydrolab® cables to connect to the Compact MS?
A: Yes. The standard Compact MS comes with the standard Hydrolab® 6 pin bulkhead connector.
Q: I do not like the standard Hydrolab® 6 pin bulkhead connector, can the Compact MS be fitted with a YSI® type connector?
A: Yes. The "Compact MS" can be fitted with an optional YSI® type bulkhead connector with recessed pins for maximum ruggedness and it will work with your existing YSI® cables.
Q: Does the Compact MS have internal memory?
A: Yes, it has enough internal memory for 120,000 measurements.
Q: Can the Compact MS be fitted with an internal battery pack?
A: No. If batteries are needed you should consider the "Compact DS"
B. The Compact DS is equipped with a 8 AA internal battery pack. The final length is 21.5" x 2.6" in diameter.
Q: Does the Compact MS require external battery power when used with the SVR4A®?
A: No, the Compact MS does not require external battery power when used with the SVR4® display.
Q: Does the Compact MS require external battery power when used with the NX8?
A: No, the Compact MS does not require an external battery power when used with the NX8.
Q: Does the Compact MS require external battery power when used with a computer ?
A: When used with a computer, the Compact MS does require external power.
Q: When connected to a Datalogger, can the Compact MS still log data internally ?
A: Yes. The Compact MS can perform all the following tasks simultaneously:
- Communicate with a PC or Handheld unit via RS232 or RS422
- Communicate to a datalogger via SDI-12 or RS232
- Log data to its internal memory up to 4 files at a time, even with overlapping dates
Q: What sensors configuration can I have on the Compact MS?
A: The Compact MS unit comes standard with temperature and conductivity/Salinity/TDS sensors and you can add any combination of the following sensors:
- pH
- Optical Disolved Oxygen
- ORP (Redox)
- TDG
