Multiparameter Portable pH/EC/DO Waterproof Meter - HI98199

Ships within 24 hours (business days)


GST and Shipping charges are extra

The HI98199 is a rugged, portable multiparameter meter with a single digital probe input. The digital probe input allows the connection of either a pH, conductivity or dissolved oxygen probe. Between the three probes and a built-in barometric pressure transducer the HI98199 can measure up to 10 water quality parameters with 5 being measured by sensors and the other 5 by calculation (i.e. EC to TDS). This professional, waterproof meter complies to IP67 standards and is supplied with all necessary accessories to measure pH/temperature packaged into a durable carrying case.

  • Digital Electrodes
  • USB-C for Data Transfer
  • Dot Matrix Display

Superior Durability

An IP67-rated, waterproof meter means that this meter is built to withstand immersion in 1m of water for up to 30 minutes. The meter has rubber gaskets sealing the battery compartment and connectors in epoxy to prevent any water from entering and damaging the internal electronics from water. With an ergonomic design and waterproofing the HI98199 will fit well in your hand and provides years of use.

Note: The meter is displayed with an optional shockproof rubber boot for additional protection.

Dot Matrix Display

The large dot matrix display provides for an intuitive user interface in which the user is guided through any setup configuration or calibration. A dedicated help key provides for contextual help that is related to the screen being viewed at the time. The dot matrix display is viewable under bright sunlight and has a backlight for when viewing under poor lighting conditions.

Alphanumeric Keypad

The low profile vulcanized rubber keypad along with virtual keys provide for a quick entry of password, user ID and sample site. The configuration of the meter can be password protected to prevent any unwanted changes. The user and sample ID are stored with any logged readings and can be transferred to a PC for analysis or long term record keeping.

Digital probes for HI98199

Digital Probes

HI98199 uses highly advance digital electrodes featuring a built-in microprocessor that performs the measurements. When these probes are connected to the meter they are automatically detected and the meter is updated to display the appropriate parameter. These digital electrodes also feature a quick connect DIN connector that provides a secure waterproof connection.


HI98199 is supplied with a pH/temperature probe. The meter can always be upgraded to measure dissolved oxygen or conductivity by purchasing the compatible probe.


The calibration information for a connected probe can be viewed at anytime using the dedicated Good Laboratory Practice (GLP) button on the meter. The calibration information includes the date, time, calibration points and probe characteristic.

HI98199 USB

Quick Connect Digital Probe Connection with Auto-Sensor Recognition

The Quick Connect DIN connector is designed for quick and secure waterproof connection. The meter will automatically recognizes the probe attached and uploads stored calibration data. Each probe then transmits readings digitally to the meter overcoming challenges faced with standard analog probes.

USB-C Port for Data Transfer

The USB-C port is used for transferring logged data to a PC using Windows compatible software. The HI98199 can log up to 45, 000 samples either by interval logging at a set time period or by log on demand of an individual reading.

Built-in Pressure Transducer

The HI98199 has a built in pressure transducer for the measurement of barometric pressure. The pressure measurement can be viewed with any probe connected but the measurement is used when measuring dissolved oxygen for automatic atmospheric pressure compensation.
