Product Information - HQ10 (Superceded)

Superceded By - HQ30

Portable LDO Meter and LDO Probe

Features

• Rugged: meet IP-67 requirements, and survive drop-test of 1-meter onto concrete.
• Easy-to-use:
  • One hand operation
  • Intuitive icons and menus
  • Large clear display with backlight
• Internal datalogging at user-selectable timed intervals and durations, of up to 500 results
• Results output at user-selectable timed intervals to a PC or printer through the optional RS232 docking station
• DO measurements are automatically corrected for:
  • Barometric pressure (the meters have a built in pressure sensor)
  • Temperature (the probes have a built in temperature sensor)
  • Salinity
• Results are displayed as either percent saturation, or as concentration (mg/L)
• User and Sample IDs can be entered, and will then be attached to the analysis record.
• The HQ20 model has an additional electrode input, for either a pH or ORP (Oxidation Reduction Potential) electrode
• These instruments meet all appropriate instrument safety and EMC regulations worldwide and bear the CE mark.

Benefits

• The DO sensor is pre-calibrated at the factory, with no additional user-calibration required for the 1-year lifetime of the sensor.
• No warm-up period for probe polarization required: plug in the probe and it's ready.
• The DO sensor is very easy to install on the probe, with no electrolyte to replace, and no cathodes/anodes to polish.
• Fast response with minimal to no stirring required.
• The replaceable sensor caps have a 1-year warranted service life.
• Much less maintenance than traditional DO probes.
• 1, 3, 5, and 15-meter cable lengths available. Integral probe weight and shroud for outdoor use.
• Locking LDO Probe connector.
• Low cost of ownership
