HI9812-51 pH/EC/TDS/Temperature Meter

Producer: HANNA Instruments

SKU: HANNA-HI9812-51 Category: Hanna experimental measuring equipment

– Handheld design, resistant to wet hands

– Measure pH, conductivity (EC), TDS, temperature with only 1 probe

– Easy to use with simple buttons.

– Manual calibration

– Automatic temperature compensation

– The meter comes with electrodes and necessary standard solutions

– Convenient suitcase for carrying the device.

– Is the new version of model HI9812-5

HANDHELD DESIGN

The meter is designed to be compact, easy to hold and sturdy in the hand

LARGE, CLEAR SCREEN

Large display shows pH, EC, TDS/temperature values along with instructions

EC/TDS CONVERSION FACTOR

Default coefficient 0.5

1-POINT CALIBRATION

– The machine has a calibration function for highly accurate and reliable results

– 1 point calibration at pH7.01 with pH knob

– Common 1-point calibration for EC/TDS at 1.41 mS/cm or 1382 ppm with EC/TDS button

hi1285-5-part-code-side-2100x2100-86a10ed3-0f82-4cc9-947d-d11ae9dc0879-3 MULTI-PARAMETER ELECTRODE pH/EC/TDS/TEMP HI1285-51

Polypropylene body has high durability, avoiding breakage or cracking due to accidental impact.

The probe is gel filled for maintenance when not in use without the need for periodic refilling. The electrode is suitable for measuring in nutrient solutions such as greenhouses, agriculture, hydroponics.

hi1285-5_tip-2100x2100-835809e0-72ce-4ba8-a49f-c7e181d496cf-4 ALL IN ONE ELECTRODES

Only 1 electrode contains pH sensor bulb, temperature sensor bar and EC/TDS sensor bar. The pH electrode's amplifier blocks moisture and electrical interference from common sources including from motors, ballasts or pumps commonly found in greenhouses.

AUTOMATIC TEMPERATURE COMPENSATION

pH, EC, TDS are all affected by temperature. The electrode with integrated temperature sensor will measure and compensate for the measured results without any further calculations.

COMPUTER CARRYING BASIS WITH FULL ACCESSORIES WITHOUT NEED TO BUY ANYTHING MORE

– The meter is supplied with full accessories in a sturdy suitcase, protecting the accessories inside when moving.

Supplied with:

– pH/EC/TDS/Temperature Electrode HI1285-51

– Calibration solution and electrode cleaning after measurement.
