Product Review: Hamilton H100

Hey! We’ll get to the Hamilton H100 in a sec, but I just want to check in with you. I’ve learned a lot about multi-parameter transmitters from these reviews and comparisons. How about you? Drop me a comment if you learned something new or if you have a question or tip about the content in general. We love to hear from you!

Anyway, these transmitters work great for pH or conductivity measurements, like in CIP or SIP processes. Do you know what those are? CIP stands for “clean-in-place,” an important procedure for cleaning inside pipes, tanks, and so on. SIP means “sterilization-in-place,” another necessary step for food and beverage processes. We’ll explain these in detail later, so stay tuned!

Okay, after they clean these systems, how do they know if the lines are completely clean? A handy-dandy transmitter installed on the line can check the conductivity of the product, which should tell you whether you have residual chemicals in the system. And where might you find such a device? Hmmm…

Today we have a new company on Visaya! Hamilton makes its debut here with an entry option from its vast portfolio, the H100 and its variations. Are you ready? Then let’s check the features and see how this device can help you!

Grab a grape popsicle, have a read, and draw your conclusions!

Whatcha got there?

As you know, these devices don’t do fancy, especially in design. They all look the same. The Hamilton H100 has a decent LCD with seven segments and icons to give you precise process data from a good distance. No backlight though, or at least I couldn’t find one on the device or in the documentation. Still, if you can get your measurements, calibration, alarms, and configuration, then you can get by, right? Well, it does those just fine.

The keypad allows you to navigate the menu tree and check the alarms and other stuff. With dimensions at 144 x 144 x 105 millimeters and weight at almost a kilogram without the accessories, it falls in line with its competitors. Not much to say here; the traditional design keeps things simple to avoid mistakes. Fair enough, I say.

Before we go any further, I should explain how the device portfolio works. The documentation on the website is a mess, but no surprise there, right? They have this standard model called the H100, then they divide the same model by applications. We have the H100 pH, H100 DO, H100 COND, and finally the H100 CONDI. I think the company wanted to organize the portfolio in an easy way. Yeah, that kinda failed.

What can it do?

Each version measures a different variable, but the Hamilton H100 product line can measure pH/oxidation-reduction potential (ORP), dissolved oxygen, and conductivity. Pretty much just like everybody else. As a 4-wire device, it needs two cables for its external power supply and two to send the signal to the control system. I prefer fewer or no wires at all, but if you’re fine with it, then it might be fine for you.

It uses polybutylene terephthalate (PBT) for its enclosure material and brings a protection level of IP65. It has no approvals for hazardous areas, but plenty of applications don’t need that anyway, and maybe yours is one of them.

We’re all about seamless integration and the Industrial Internet of Things here, but we have to put those ideas aside for an entry-level device. Still, the HAMILTON H100 has no digital protocol, and most competitors offer entry devices with HART at least.

Why should I care?

Because the Hamilton H100 can do the job, simply and cheaply. Some people need that, and maybe you do too. Wait, we have a tiny bonus! It comes with Sensoface technology, where the transmitter can check sensor conditions such as the zero/slope, calibration interval, and response time. It also has Sensocheck, a feature for monitoring open and closed circuits. Okay, two bonuses. Bonus and a half? You tell me.

In general, the device provides all information you expect, and the configuration experience is not bad. Of course, if it at least had HART communication, then you’d have an option to avoid going into the field, but hey. Them’s the breaks.


The HAMILTON H100 sounds like a good option cost-wise. If you want a simple device and don’t need many features, you can consider this one. It has a good interface, display, and basic diagnostics. Check it against the other reviews, scale it out, analyze the cost benefits, and make your choice. Or wait for our comparison! It’s coming up!
