Hanna HI98319 Marine Salinity and Temperature Tester

Hanna HI98319 Marine Salinity and Temperature Tester is used to measure the salinity and temperature of natural and artificial seawater in aquariums.

Designed for Simple Aquarium Salinity Testing

Hanna Instruments HI98319 Marine Salinity Tester measures electrical conductivity (EC) to determine the salinity of natural and artificial seawater. Within seconds, the salinity and temperature are measured, and then using the temperature reading, automatically compensated and displayed on the easy-to-read LCD screen. Ensuring the proper salinity in your reef tank allows your fish and corals more time to grow instead of having to adjust to constant salinity changes. If you have a hard time seeing the fuzzy blue line common with traditional refractometers or just want to make your life easier, pick up a Hanna HI98319 Salinity Testing Pen!

premium feel in the hand.
Can't really say whether it's that good or not elecronics wise since I didn't test it but it works like it's supposed to. Meanwhile, the housing oh man. It's premium. It feels like hard aluminum or something, very nice. Edges are rounded too with just the right sharpness like a macbook. Others would've been plastic. This is really nice for the price and if the specs really are 10Gbps, that's really good because most in this price range is 5Gbps.

Failed to support desktop PCs with USB 3.2 Gen 2 ports
Does not work with my HP mini PC with USB 3.2 gen 2 ports - when connecting USB portable SSDs to the hub. You won't believe it, but many USB 3.2 Gen 2 hubs only support laptops not desktop PCs (except hubs that have dedicated power supply for higher power USB devices e.g. SSD/HDDs) when connecting USB portable SSDs to the hub. We need a major fix from many of the USB hub vendors so these products can work with desktop PCs that have USB 3.2 Gen 2 ports. Workaround: Just directly connect the USB portable SSD to the PC instead. If you need more USB ports, pick up a good old USB 3.0 hub. They're working correctly with portable USB SSDs when working with desktop PCs. (You'd need a powered USB hub if you're connecting 2 or more portable SSDs - do your own calculation: 5V - 1A per SSD/HDD).

Need more USB-C ports AND passthrough power?
Style: 4-in-1 USB-C Hub
This hub is very handy if you need to use multiple USB-C peripherals but still need passthrough power for your laptop, 65 watts in my case. I have not experienced any noticeable difference in transfer speeds or heat. Typical Belkin high quality, all the ports are tight and connections feel secure. I want to note that this unit will NOT allow HDMI functions via USB-C. I still need to plug my external display directly into the other USB-C port on my laptop. The only downside is that the surface of the hub is a high gloss black, which will scuff like crazy the first time you toss it into your backpack or set it on the table. Does not at all effect functionality but can be annoying for some. Otherwise, this is now one of my essential daily tech accessories.
