A high quality 40mm clear visibility bubble level ideally designed for audio applications such as turntable. These vials are made to the highest standards and they have a reliable and repeatable bubble movement and consistent sensitivity. This is due to the high quality moulding, and the cleanliness of the internal surfaces and the liquid, and the tight control over the bubble size and the rest of the manufacturing process.

Suspended turntables are designed so their suspensions work in the vertical plane to give "pistonic" motion usually tuned well below audio frequency. If the table is out of true the "pistonic" motion picks up all sorts of parasitic motions, wobbling all over the place sometimes in the audible range (>20hz) and at the frequency of record warps. This is why quality suspended tables take so long to set up - to get the bounce spot on - if the turntable isn't level the bounce will NEVER be right.

One of the critical components for a turntable is the main bearing which must offer minimal friction and hold the platter fixed in all planes except rotation - all this with minimal play and as little vibration as possible. All such bearings are designed to work with the turntable level with all forces acting vertically downwards. Tilt the table and you add a horizontal force which will compromise performance and over the long term cause the bearing to wear unevenly, non-suspended turnables often have very heavy platters which exacerbates the problem


These instruments should not be confused with the cheap Far East origin lookalike products often seen on eBay. These are quality vials for applications that actually need to be set level within a specific degree of accuracy.
The bubble spirit level complies with all EU Regulations including RoHS, REACH and Conflict Mineral Certification.
