The Comandante Coffee Tray was created specifically for use in coffee shops and roasting facilities. It can also be used for cupping and holds about 250g of green coffee. You can dose the coffee to perfection because of the funnel form. In the middle of the shell is an embossed version of the Comandante logo. Because it is made entirely of recyclable materials, the shell is both strong and light.

Calibration Buffer Solutions-Hanna Instruments
Maximum accuracy is high on the agenda here at Hanna. Browse our Conductivity Calibration Solutions specifically produced for Conductivity meters and electrodes.
Hanna conductivity electrodes can be calibrated in just a few minutes, wherever you are working, thanks to our range of conductivity solutions in different forms and values. Sachets, for instance, could be very useful out in the field as well as the laboratory.
Each label shows the product batch number, expiry date, and a conductivity/temperature correlation table. EC value is calculated at 25C.
HI770710P is a set of premium quality pH 7.01 and 10.01 calibration buffers produced in accordance with ISO 3696/BS3978 standards using high purity salts, deionized water, certified weight-checked balances, and Class A glassware in a temperature controlled environment monitored with certified thermometers. Reported values are accurate to +/- 0.01 pH @ 25°C and are traceable to NIST Standard Reference Materials (SRMs).

Convenience of individual packaging
• Ideal for users that do not calibrate frequently
• Ideal for field use due to portability
• Every sachet is as fresh as the day it was packaged
• Light block packaging prevents oxidation from UV light that could alter the buffer value

Each sachet marked with lot number and expiration date.
• Hanna buffers are specially formulated to have an expiration of 5 years from manufacture for an unopened sachet.

Light block packaging
• Prevents any oxidation from UV light that could alter the buffer value.

Color coded label for easy pH buffer value identification.
• Easy to identify different buffer values
• Solution does not contain any dyes that may stain the reference cell of a pH electrode

The HI98129 is an easy-to-use and accurate waterproof pH, conductivity, TDS (ppm) tester. It measures pH, EC in the low range (0 to 3999 µS/cm), TDS (0 to 2000 ppm), and temperature. This floating, waterproof combination pocket tester has an easy to read, LCD and an automatic shut-off. All pH, EC, and TDS (ppm) readings are automatically temperature compensated (ATC) to prevent temperature-related variations in your measurements. For EC and TDS (ppm) readings, the EC/TDS conversion factor (CONV) is selectable by the user, as well as the temperature compensation coefficient β (BETA).

Replaceable pH Electrode Cartridge
The HI98129 tester features an easy to replace pH electrode cartridge with an extendable cloth junction. The extendable cloth junction helps increase electrode life and the replaceable pH cartridge means that this tester does not need to be thrown away when the pH sensor is exhausted. Also, the sturdy, snap-in connector means there are no pins to bend or break!

High Accuracy EC and TDS (ppm) Tester Probe
The graphite conductivity probe provides greater accuracy because it cannot be contaminated by salt deposits in the solution. The exposed temperature sensor provides fast response times and guarantees highly accurate temperature compensated readings.

Features at-a-glance
• 3 sensors in a single tester
• pH electrode with extractable junction
• Amperometric EC/TDS sensor
• Exposed temperature probe for faster EC and TDS (ppm) readings

Waterproof
• Designed to float if accidently dropped in sample

Wide pH Range
• pH range is from 0.00 to 14.00 pH

Selectable EC to TDS (ppm) conversion factor
• Choice of either a 0.45 or 1.0 conversion factor

Automatic Temperature Compensation
• All readings are compensated for variations in temperature
• Temperature displayed in oC or oF along with pH, EC or TDS reading

Stability indicator
• Meter displays a clock tag that will disappear when the reading has achieved stability

HOLD button
• Freezes reading on the display to allow recording of measurement

BEPS (Battery Error Prevention System)
• Meter will automatically shut off if there is not enough power to get an accurate measurement

Battery % level at startup
• Low Battery Indicator
• When the level is below 5%, the  battery symbol on the LCD blinks to indicate a low battery condition.

Auto-off 
• Auto-off  feature automatically shuts off  meter after 8 minutes of non-use to maximize battery life
