Sinometer HY3005D Variable Linear Lab Power Supply 0-30V 0-5A Review

I use a number of different types of variable voltage bench power supplies. I run a small company and we cannot afford top of the line equipment and we do not require government calibrated units. My company works on electronic and software designs and I have not only used this unit extensively I have also taken the cover off and looked at the internal design, not because there was an issue, but to compare it to a similar looking unit that had a very bad design which failed hence needing to purchase this replacement.

We use these PSUs to power small dc devices that we need to test at a specific voltage and current. In most cases we are running at fairly high percentage current draws of 3-4Amps and switching the equipment on and off repeatedly throughout the day. Although we always ramp the voltage up before turning it on and down before turning it off, the unit gets a lot of use perhaps 20 -30 cycles a day.

To date the unit has proved reliable and although the heatsink gets warm, there is nothing cooking under the hood and the unit reliably and consistently delivers the set voltage and current required for the tests. Inside the unit is professionally manufactured with a well thought out layout, good circuit design and professional component soldering and connections unlike some other similar units on the market.

Overall I am very pleased with this PSU, consider it good value for money and would recommend it to others.

Product Description

The Hanna Instruments HI 98103 is a compact pH tester with a narrow probe for use in small samples or test tubes, and has manual two-point calibration, a single-line LCD screen, a replaceable electrode, and low power demand. A pH meter is commonly used to measure the pH of substance such as water, food, beer, or wine in laboratory, industrial, and food applications. The single-line LCD screen of this meter shows the current measurement. The meter has manual temperature compensation and manual two-point calibration through trimmers on the top. Two 1.5V AA batteries provide approximately 3000 hours of use. The meter also comes with an HI 1270 pH electrode and instructions.

Specifications

pH range	0.0 to 14.0
pH resolution	.01
pH accuracy	+ or - .2
Operating temperature	-5 to 50 degrees C (23 to 122 degrees F)
Operating relative humidity	95 percent
Dimensions	66 x 50 x 25mm/2.6 x 2.0 x 1.0 inches (H x W x D)

H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

A pH meter, also called a sensor or tester, is a device used to measure the acidity or alkalinity of a substance. A pH meter has either a portable or a benchtop body. Many portable meters are handheld devices. Some testers have an internal sensor, and may have a tip and body that fit inside of a container for measurement. A meter is commonly used in many different environments from laboratories to field research and manufacturing facilities. Researchers, manufacturers, and hobbyists use a pH meter in aquaculture, agricultural, wine-making, and water-testing, and for scientific applications. Some pH meters may measure additional parameters such as dissolved oxygen (DO), conductivity (also called electro-conductivity or EC), temperature, total dissolved solids (TDS), salinity, resistivity, or oxygen reduction potential (ORP)/mV.

Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) standard 9001.

Hanna Instruments HI98103 Checker pH Tester with pH Electrode and Batteries, 0.00 to 14.00 pH, +/-0.2 pH Accuracy, 0.01 pH Resolution Review

I use this at home for brewing small batches of wine. It is very good for the price, especially if you are only using it intermittently. This meter needs to be re-calibrated each time you use it. I would also suggest testing the endpoints in your calibration 3-4 time to ensure reliable measurements. Measurements can take upward of 15-20 seconds to stabilize. Do not expect this meter to respond quickly to pH changes if attempting to pH adjust with chemical additions.

Having (previously) worked in chemical research labs for close to 15 years, I'm used to a more accurate and responsive pH meter. Given it was only $30, I'm OK with the extra effort and limitations. Considering that more reliable home use pH meters start at $130, this is a great starter for most hobbyist.

I purchased these for my son's Mad Science Birthday party. They were GREAT! Loved the colors and the stand they came in. Futures buyers beware that they do hold skittles and nerds well, however, m&m's are too wide as were nerd jelly beans. They were perfect favors and I would recommend.
