Damages due to accident, misuse, tampering or lack of 

prescribed maintenance are not covered. 
If service is required, contact the dealer from whom you 

purchased the instrument. If under warranty, report the model

number, date of purchase, serial number and the nature of the

failure. If the repair is not covered by the warranty, you will be

notified of the charges incurred. If the instrument is to be

returned to Hanna Instruments, first obtain a Returned Goods

Authorization Number from the Customer Service department

and then send it with shipment costs prepaid. When shipping

Dear Customer,
Thank you for choosing a Hanna product. This manual will 
provide you with the necessary information for the correct
operation of the meter. Please read it carefully before using
the meter. If you need additional technical information, do not
hesitate to e-mail us at tech@hannainst.com or call 
1-800-426-6287.  This instrument is in compliance with 
directives EN 50081-1 & EN 50082-1.

Remove the instrument from the packing material and 
examine it carefully to make sure that no damage has
occurred during shipment. If there is any damage, notify 
your Dealer.
Each C 219 instrument is supplied complete with 
• Two 9V Batteries
• One Light Shield Cap
• One Transport Cap
• 12 VDC Transformer (HI 710005 or HI 710006)
Note: save all packing material until you are sure that the
instrument works correctly. Any defective item must be 
returned in its original packing.

The C 219 instrument measures the percent light transmittance
of maple syrup as compared to analytical reagent glycerol. The
transmittance value allows identification of syrup quality class.
Measurements are done by using matched square optical
cuvets having a 10 mm light path.
Display codes aid the user in routine operations. 
The meters have an auto-shut off feature that will turn the
instrument off after 10 minutes of non-use.

The primary characteristic for classifying maple syrup is color.
When syrup is very light in color, as matching the minimum light
transmittance standards, the grade assigned to syrup is high.
When syrup color is dark, the grade is low. Color classes are
expressed in percent of light transmission as compared to an ana-
lytical glycerol standard fixed at one hundred percent transmis-
sion. All syrup is considered to be at minimum density, 66.0
degrees Brix at 68 degrees  F (20

0

C), and to have no flavors 

nor other characteristics extraneous to pure maple syrup.

Hanna Instruments reserves the right to modify the design, 

construction and appearance of its products without advance notice.

This indicates that the meter is in a ready state and
calibration can be performed.

Sampling in Progress. This flashing prompt appears
each time the meter is performing a measurement.

The microprocessor is adjusting the light level, indi-
cated by a scrolling “SIP”.

This indicates that the meter has been calibrated
and measurement can be performed.

Calibration was not performed. Follow the instructions
described in the measurement procedures for 
calibrating the meter.

The instrument is performing an internal check-up.

The instrument cannot adjust the light level. Please
check that the sample does not contain any debris.

There is not enough light to perform a measurement.
Please check the preparation of the Glycerol cuvet.

There is too much light to perform a measurement.
Please, check the preparation of the Glycerol cuvet.

There is too much light for the sample measurement.
Please check if the right sample cuvet is inserted.

The sample and Glycerol cuvet are inverted.

The blinking "LOBAT" indicates that the battery voltage
is getting low and the battery needs to be replaced.

This indicates that the battery is dead and must be
replaced.

Light over range. The cuvet is not inserted correctly
and an eccess ambient light is reaching the detector.
If the cap is properly installed, contact your 
dealer or the nearest Hanna Customer Service Center.

This indicates that the calibration procedure failed
due to a low signal-to-noise ratio. In this case press
CAL again. Or, it may indicate over range: a flash-
ing 100.0% value as result of a reading 
indicates that the sample absorbs less light than
the glycerol standard.
