Tap water response(after three months)
(old)
In the past…
Electrode hit stirrer or beaker and broke
In the past…
Calibration in room temperature→measurement at 37℃pH0.1 error against pH4 solution
Built-in Temperature SensorReliable measurement!
3. High Precision
1. No sample contaminationIn the past…Internal solution ooze out from Liquid junction, contaminating the sample
Ag+ Trap Technology
No contamination!
2. UnbreakableToupH DesignStrength even breaking the beaker!
Micro ToupH (9669-10D)World’s smallest w/temp. sensor
In the past…Enough volume of precious or large container has to be prepared
3mm diameter sensorRequires only 0.3ml of your sample
4. For microvolume or Precious samples
In the past…
Electrode hit stirrer or beaker and broke
1. No sample contaminationIn the past…Internal solution ooze out from Liquid junction, contaminating the sample
Ag+ Trap Technology
No contamination!
2. UnbreakableToupH DesignStrength even breaking the beaker!
ToupH Sleeve (9677-10D)Ideal for viscous or slurry sample
In the past…
Hard to measure viscous sample (does not come in contact with liquid junction) or slurry sample (clogs the liquid junction)
3. Works with difficult samplesSlurry DesignViscous sample still contacts with liquid junction, cleaning is also easy
1. Easy maintenance
3. Minimize running cost
・ No need to replace or refill KCl internal solution ・ Just replace a tip when sensor is consumed
Easy to use
・ Food additives (CMC, Glycerine, KCl) is used for internal solution・ Glass will not break into sample (food)・ Tip design allows for easy sample entry
・ Replaceable tip makes it economical and environmentally friendly.
2. Ideal for food measurement
For meat and fruit
Just replace the tip!
ISFET Electrode (0030-10D)Ideal for food measurement
Cleaning ReagentModel #220
10% Thiourea, 1% HCl
Over 50% of electrodes recovers, based on HORIBA experience.
Effective for liquid junction cleaning, removing contamination from inorganic sample
